A worksheet you can explain.

Ten study missions turn the lessons into calculation sheets, drawing counts and clear handoff notes.

Worked example · Calculation mission

Choose the relationship. Check the units.

For the supplied ideal 12 V / 24 ohm paper model:

I = 12 / 24 = 0.5 A
P = 12 × 0.5 = 6 W

Reasoning: doubling resistance to 48 ohms halves current to 0.25 A.

Next attempt: use 18 V and 36 ohms. The checks are 0.5 A and 9 W.

Example from the existing exercise and answer guide.

A drawing count: E2.1 revision B totals six A and three S. Label the revision and flag X for clarification.

A handoff note: identify the supplied instruction, name what is unconfirmed and ask for the current task boundary and supervision.

A complete first-skill preview

Try Circuits, Ohm's law and power

Learn the ideas, check your understanding, then solve five paper calculations. Read the explanations and try again until you can explain your answers.

Your outcome: calculate amps, ohms and watts, compare series and parallel circuits, and explain how current changes resistive heating.

Paper calculations only. You do not need equipment or live measurements. A free account can save this practice result. It stays separate from your paid skill progress.

1. Learn the six key ideas

Three quantities

Voltage (V, in volts) is the push. Current (I, in amps) is the flow. Resistance (R, in ohms) is what holds the flow back.

Ohm's law

V = I × R. Turn it around when you need another value: I = V ÷ R and R = V ÷ I.

Power

Power (P, in watts) is how fast energy is used. P = V × I. Put Ohm's law into it and you also get P = I² × R and P = V² ÷ R.

Series

One path. The same current flows through every part, and the resistances add up.

Parallel

Separate paths. Every branch has the same voltage, the branch currents add up, and the total resistance is lower than the smallest branch.

Why it matters on the job

Heat in a wire or a connection grows with current squared (I² × R). That is why an overloaded circuit or a loose connection runs hot.

For these resistive examples, use V = I × R and P = V × I. When using AC values here, treat the stated voltage and current as RMS values.

Sources: OpenStax 9.4 Ohm's Law · OpenStax 9.5 Electrical Energy and Power · OpenStax 10.2 Resistors in Series and Parallel

2. Check and apply: five questions and five calculations

Check your understanding

1. A heater element has 60 ohms of resistance and 120 volts across it. How much current flows?
2. In a series circuit, which value is the same through every part?
3. You add one more resistor in parallel with a resistor that is already connected. What happens to the total resistance?
4. A 1,500 watt space heater runs on 120 volts. About how much current does it draw?
5. The current through a wire doubles and its resistance stays the same. What happens to the heat made in the wire?

Apply it on paper

    Find the scale in the title block first.

  6. Step 6. Say the six fixtures run at 120 volts. Using the fixture schedule, how much current do they draw together?
    Show a hint

    Add up the watts from the schedule, then use I = P ÷ V.

  7. Step 7. Materials: how many wall device boxes do you need for the receptacles and switches?
    Show a hint

    One box per receptacle and one per switch.

  8. Step 8. One fixture has a detail callout marked 3 over E5.1. Where do you look to see how it is supported?
    Show a hint

    The detail number is on top, the sheet number below.

  9. Step 9. Before you order or install anything, which questions do you take to your supervisor? Tick every one that applies.
    Show a hint

    Ask about what does not match, what is missing, and what keeps you safe. Skip what the legend already answers.

Leer fracciones en una regla

Lección completa gratuita · Lee, razona, compara y vuelve a intentar

Revisa primero: No requiere una lección anterior.

Comprende el concepto

Divide una pulgada en 16 partes iguales. Simplifica una fracción dividiendo numerador y denominador por el mismo número. Suma longitudes con denominador común y conserva las unidades. La pantalla puede cambiar la escala: lee las marcas rotuladas, no midas la imagen con una regla real. Guía original de tres viñetas: identifica cero y unidad; alinea los dos extremos de papel con la escala; resta inicio a final y registra unidad. El borde no siempre es el cero. El dibujo enseña lectura, no calibración de pantalla. Para una medida opcional de aula, usa solo papel y regla legible; el instructor suministra longitud de referencia y tolerancia antes de empezar. No hace falta cuchilla, cableado ni herramienta de construcción.

Práctica con papel y regla; manejo supervisado de cinta

Desarrolla la habilidad con demostración, intento controlado y revisión observada. Son estaciones de la formación existente, no requisitos adicionales de licencia. Los productos identifican ejemplos; usa equipo compatible disponible con tu proveedor.

Preparar la estación

Regla legible, tira de papel, lápiz y referencia del instructor. Para cinta retráctil, sigue sus instrucciones; nunca midas la pantalla.

Inicio 1 1/8 → final 5 3/8 inInicio 1 1/8 → final 5 3/8 in
Esquema original simplificado, sin escala; las instrucciones del modelo real controlan la operación.

Observar, explicar y demostrar

  1. Identifica unidad y división mínima. Localiza cero independientemente del borde. Coloca ambos extremos del papel junto a la escala sin doblarlo.
  2. Lee de frente. Escribe inicio y final antes de restar. Si el inicio no es cero, réstalo; la lectura final sola no es longitud.
  3. Marca suavemente desde la referencia acordada. Vuelve a medir tras levantar y recolocar la regla. Conserva ambos resultados, incluido el fallido.
  4. Compara con límites del ejercicio y explica diferencias con denominador común. Con cinta, controla el retorno según su modelo; aleja la hoja de personas y no la dejes golpear al retraerse.

Tu intento controlado

Lo que observa el revisor

  1. Localizar cero, unidad y división mínima.
  2. Registrar ambos extremos y resta.
  3. Conservar repeticiones reales con unidades.
  4. Decidir con límites suministrados, sin calibrar por pantalla.

Detener y volver a enseñar

Escala dañada, cinta incontrolada, referencia incierta o tolerancia ausente: pausa y aclara antes de evaluar.

Un error crítico detiene el intento independientemente de respuestas escritas. Reenseña la operación y observa un nuevo intento; no compenses fallo de seguridad con promedio.

Mueve el inicio a 1 1/8 in y final a 5 3/8 in; después usa otra pieza real.

Estas lecciones complementan las siete habilidades básicas, dos escenarios y diez misiones existentes. ET Member incluye la colección completa de estudio para ayudantes. Los resultados básicos y de herramientas profesionales conservan sus registros de cuenta. Guarda tus notas en TXT y lleva el archivo a la próxima sesión.

El estudio en línea y la práctica supervisada se complementan. Estas lecciones preparan tu razonamiento y preguntas; el empleador o proveedor enseña y evalúa las tareas físicas reales.

Empieza aquí: de tu experiencia actual al puesto de ayudante

Tu puesto anterior no impone una ruta eléctrica distinta. Usa lo que puedas demostrar y practica las mismas bases de ayudante. Si no tienes ejemplo laboral pertinente, utiliza un ejemplo de estudio claramente identificado.

  1. Prepara tu expediente de ingreso. Usa H01 función y estado y H02 comparación de vías y borrador de solicitud. Conserva una vía principal y una alternativa, cada una con fuente y próxima acción propias.
  2. Practica las habilidades iniciales comunes. Prueba M01 fracciones gratis. Continúa con matemáticas, seguridad, herramientas/materiales, planos y comunicación. Revisa requisitos previos y conserva las comprobaciones resueltas.
  3. Prepara el primer día. Usa S02 preguntas de inducción y EPP y C01 confirmación clara de instrucciones. Confirma con el empleador el puesto real, supervisor e instrucción específica de la tarea.
  4. Conserva un registro de la primera semana. Combina H03 registro de trabajo y estudio con C04 expediente de ocho partes. Guarda el trabajo escrito en TXT antes de salir.

Inventarios de tienda, relevos de hostelería, control documental de oficina y recepción de almacén aportan ejemplos útiles. No transfieren automáticamente competencia eléctrica. Otras experiencias siguen el mismo enfoque de tarea y evidencia.

Usa la guía pública de ayudante y casos prácticos junto a esta colección. La lección completa de fracciones es gratuita; las demás conservan el acceso ET Member existente.

Esta es la primera etapa: tu experiencia actual → ayudante eléctrico. Después: ayudante → Journeyman → Master → contratista. Cada etapa tiene requisitos propios; una hoja completada no otorga licencia, empleo ni ascenso.

Planifica la parte supervisada de tu aprendizaje

Combina estas lecciones con instrucción práctica del empleador o proveedor. Pregunta qué practicarás, quién supervisará y cómo se evaluará:

  • Herramientas manuales y eléctricas: identificación, estado, uso y mantenimiento.
  • Canalizaciones, soportes, cajas y conductores: replanteo, doblado, preparación, tendido y ajuste asignados a tu función.
  • Conexiones y calidad: preparación, requisitos de apriete, inspección y revisión real.
  • Instrumentos: categoría y accesorios adecuados, estado, uso autorizado e interpretación.
  • Seguridad: EPP, acceso, materiales, función aplicable de control de energías y emergencias.

Separa estudio, demostración observada, práctica supervisada y desempeño evaluado. Registra tarea y función del revisor, sin autoasignarte competencia general.

Compara las vías de formación de Texas; el proveedor o empleador confirma admisión, disponibilidad y formación reales.

Cómo se organiza esta ruta de estudio

El mapa toma como referencia temas publicados de NCCER Core y Electrical Level 1, tareas de ayudante O*NET y fuentes oficiales de Texas/OSHA enlazadas. Es una ruta independiente, no un curso o credencial NCCER ni sustituto del aprendizaje profesional.

Elige la lección de tu próxima tarea. Revisa requisitos, explica el primer caso, compara la guía, intenta el caso modificado y conserva tu siguiente paso. Un ejercicio escrito demuestra estudio, no licencia ni evaluación de competencia de campo.

Your next practice

From a plan task to a worksheet you can explain.

The free task lets you try the drawing. ET Member adds these existing study missions: write your reasoning, check it against the guide and try a changed problem.

Existing mission · worked example

A count sheet that names its source.

A count sheet identifying the source revision and one question to confirm.

Example result: Room 104: A = 4, S = 2. Room 105: A = 2, S = 1. Totals: A = 6 and S = 3.

See the task, worked answers and changed problem

1. Read the supplied extract

Fictional extract E2.1 revision B: legend A = light fixture, S = switch. Room 104 lists A, A, A, A, S, S. Room 105 lists A, A, S. An old revision A note says Room 104 had three A symbols. Do not use these invented symbols on another drawing.

  1. Count A and S in each room, then total each type.
  2. Which Room 104 count belongs on a sheet based on revision B, and why?
  3. A label X appears in a later note but not in this legend. What should your handoff say?

2. Compare the worked answers

  1. Room 104: A = 4, S = 2. Room 105: A = 2, S = 1. Totals: A = 6 and S = 3.
  2. A = 4 for Room 104, because that is the supplied revision B extract. Record E2.1 revision B; do not mix the older count into the new sheet.
  3. Mark X as unresolved and ask for the applicable legend or clarification. Do not silently treat it as a fixture or switch.

3. Check the reasoning

  • Label the source E2.1 revision B and keep the room counts separate.
  • Total A and S separately; leave X unresolved until its legend is confirmed.
  • Recalculate with revision C and label the revision on the new count.

4. Try the changed condition

Revision C explicitly changes Room 105 to three A symbols and leaves all S symbols unchanged. Recalculate the totals and name the revision.

Check the changed count

E2.1 revision C: A = 7 and S = 3. The changed count is not evidence of an approved installation design.

5. Keep the example worksheet

The TXT below contains these worked answers and finish checks. In a member mission, your download contains your own written notes.

WORKED EXAMPLE - existing drawing-count mission
Turn a drawing extract into a checked count
Fictional extract E2.1 revision B: legend A = light fixture, S = switch. Room 104 lists A, A, A, A, S, S. Room 105 lists A, A, S. An old revision A note says Room 104 had three A symbols. Do not use these invented symbols on another drawing.

1. Count A and S in each room, then total each type.
Room 104: A = 4, S = 2. Room 105: A = 2, S = 1. Totals: A = 6 and S = 3.

2. Which Room 104 count belongs on a sheet based on revision B, and why?
A = 4 for Room 104, because that is the supplied revision B extract. Record E2.1 revision B; do not mix the older count into the new sheet.

3. A label X appears in a later note but not in this legend. What should your handoff say?
Mark X as unresolved and ask for the applicable legend or clarification. Do not silently treat it as a fixture or switch.

Finish checks:
- Label the source E2.1 revision B and keep the room counts separate.
- Total A and S separately; leave X unresolved until its legend is confirmed.
- Recalculate with revision C and label the revision on the new count.
Try again: Revision C explicitly changes Room 105 to three A symbols and leaves all S symbols unchanged. Recalculate the totals and name the revision.
Worked second attempt: E2.1 revision C: A = 7 and S = 3. The changed count is not evidence of an approved installation design.
Next study step: repeat the count using the stated revision and keep the source label with the result.
