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.

An estimate with costs, assumptions and a stated pricing model.Un presupuesto con costos, supuestos y modelo de precio explícito.
Study model · supplied fictional valuesModelo de estudio · valores ficticios dados
In a simplified study estimate, margin uses selling price as its denominator; markup uses cost. Write what is included and excluded before trusting a percentage. Use supplied fictional values, not a market-rate recommendation.En un presupuesto simplificado, el margen usa precio de venta como denominador; el recargo usa costo. Escribe inclusiones y exclusiones antes de confiar en un porcentaje. Usa los valores ficticios dados; no son tarifas recomendadas.
Paper model: materials $6,000, labor $4,000 and allocated overhead $1,000. The model target is 20% margin on selling price. Tax, financing, contingencies and job-specific requirements are not modeled.Modelo: materiales $6,000, mano de obra $4,000 y gastos generales asignados $1,000. La meta del modelo es margen de 20% sobre venta. No incluye impuestos, financiación, contingencias ni requisitos específicos del trabajo.

Inside the existing member workbook
Ten study missions turn the lessons into calculation sheets, drawing counts and clear handoff notes.
Worked example · Calculation mission
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.
In each mission: write your reasoning, compare it with the guide, try the changed problem and keep your next study step.

A complete first-skill preview
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.
Voltage (V, in volts) is the push. Current (I, in amps) is the flow. Resistance (R, in ohms) is what holds the flow back.
V = I × R. Turn it around when you need another value: I = V ÷ R and R = V ÷ I.
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.
One path. The same current flows through every part, and the resistances add up.
Separate paths. Every branch has the same voltage, the branch currents add up, and the total resistance is lower than the smallest branch.
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.

Your foundation and career-tool results keep their existing account records. Keep written lesson notes as TXT; bring the file to your next session.
Online study and supervised field practice work together. These lessons prepare your reasoning and questions; your employer or training provider teaches and assesses actual physical tasks.
Your previous job does not choose a separate electrical route. Use what you can already demonstrate, then practise the same helper foundations. If you have no relevant job example, use a clearly labeled study example.
Retail stock checks, hospitality handoffs, office document control and warehouse receiving can supply useful evidence examples. They do not automatically transfer electrical competence. Other backgrounds use the same task-and-evidence approach.
Use the public helper guide and practice cases alongside this collection. The full fractions lesson is free; the other linked lessons keep their existing ET Member access.
This is the first stage: your current background → electrical helper. The later learning stages are helper → Journeyman → Master → contractor. Each has its own requirements; completing a worksheet does not confer a license, job or promotion.
Use these desk lessons alongside hands-on instruction through your employer or training provider. Ask what you will practise, who will supervise and how performance will be assessed:
Keep study, observed demonstration, supervised practice and assessed performance separate in your own records. Record the specific task and reviewer role rather than awarding yourself general competence.
Compare existing Texas training routes; actual admission, availability and training are confirmed by the named provider or employer.
The lesson map draws on the published topic areas in NCCER Core and Electrical Level 1, O*NET helper work, and the official Texas and OSHA sources linked in the lessons. It is an independent study route, not an NCCER course, credential or substitute for an apprenticeship.
Choose the lesson for your next task. Review its prerequisites, explain the first case, compare the guide, try the changed case and keep your next-step note. A finished paper exercise is study evidence, not a license or field-competence assessment.

Existing mission · worked example
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.
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.
Revision C explicitly changes Room 105 to three A symbols and leaves all S symbols unchanged. Recalculate the totals and name the revision.
E2.1 revision C: A = 7 and S = 3. The changed count is not evidence of an approved installation design.

ET Member - study worksheet 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.
