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.

See two more worksheet outcomes

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

Read the plan. Prepare a clear handoff.

Use the same practice drawing and nine steps as the existing member activity. Count devices, follow circuit labels, work at scale and list what to confirm with your supervisor.

What you make: a practice plan sheet with device counts, a lighting-load calculation and questions to confirm before work.

Complete public sample. No account or payment needed. Answers stay on this page and clear when it reloads. This is paper practice, not a work instruction, approved design or proof of job competence.

New to drawing practice? Open the drawing larger to read its legend. Each question has Show a hint; use it before answering. If the load calculation is new, learn Ohm's law and power in the free first skill, then return here. Work at your own pace; you can check an incomplete attempt for feedback.

Try the complete 9-step plan task

Your foreman hands you sheet E2.1 and says: "Room 104 is yours tomorrow. Tell me what is in there and what you need." Read the plan below, then answer each step.

Practice drawing E2.1 for Room 104: device symbols, circuit labels, dimensions and fixture schedule
Sheet E2.1, Room 104 Break room (practice plan drawn by us). Open the drawing larger to read the legend. Use the scale stated in the question; the image on your screen is not a full-size print.
  1. Step 1. How many type A light fixtures are on the plan?

    Home run numbers name a panel and a circuit.

  4. Step 4. What controls the lights?
    Show a hint

    Look up S3 in the legend.

  5. Step 5. On the full-size print, receptacle R1 measures 1-1/2 inches from the west wall. How far is that on site?
    Show a hint

    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.

Bring your experience. Build your helper skills.

43 desk lessons, from fractions and electrical concepts to drawings, materials and a clear handoff. Each lesson gives you a worked example, a changed problem and questions to take into supervised training.

Try the fractions lesson free ↗

These lessons complement your existing seven foundation skills, two scenarios and ten study missions. Continue with ET Member for the full helper study collection. 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.

Start here: from your current work to a helper role

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.

  1. Prepare your entry folder. Use H01 role and status and H02 route comparison and application draft. Keep a primary route and a backup, each with its own source and next action.
  2. Practise the common starting skills. Try M01 fractions free. Continue with the mathematics, safety, tools/materials, drawings and communication groups below. Review prerequisites and keep the worked checks.
  3. Prepare for day one. Use S02 induction and PPE questions and C01 a clear repeat-back. Confirm the actual role, supervisor and task-specific instruction with the employer.
  4. Keep a first-week record. Combine H03 your work/study log with C04 your eight-part entry folder. Download written work as TXT before leaving.

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.

Plan the supervised part of your learning

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:

  • Hand and power tools: identification, condition checks, appropriate use and maintenance.
  • Raceways, supports, boxes and conductors: layout, bending, preparation, pulling and fitting tasks assigned to your role.
  • Connections and quality: preparation, tightening requirements, inspection and review of actual work.
  • Test instruments: suitable category and accessories, condition, authorized use and interpretation.
  • Site safety: PPE, access, materials handling, the applicable energy-control role and emergency arrangements.

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.

How this study route is organized

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.

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.

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.

Questions before you start

Is the account free?

Yes. Save your Texas starting checklist and use the basic learning record and planning tools in your free account. ET Member adds the foundation activities and the extended review features listed in the comparison above.

Does the public skill preview save my answers?

Try the preview and read the feedback without an account. A free account saves your latest first-skill answers, scores and review list. This saved preview is separate from paid foundation progress.

ET Member includes seven foundation skills, two guided scenarios, ten study missions with TXT worksheets, the Texas job-search pack and saved review tools. It also includes extended exam practice history, weakest-topic summaries and learning-record exports. Your basic hours ledger and career-planning tools remain free.

Why return after the first week?

Does this qualify me to work as an electrician?

No. These are online foundation learning and practice activities. They do not award a trade licence, verify field competence or replace supervised training.

Can I use it on my phone?

Yes. The account pages fit phone and desktop screens, so you can study or log hours wherever you are.

What can I track?

Track practice progress, focus topics, your exam date, supervised hours, license milestones and career goals.
