Quick start

Study tools

Best daily routine

Complete your question goal, do five timed code lookups, then review missed questions or flashcards. Use the full exam after your topic accuracy is consistently above 70%.

Topic Mastery

Weakest areas

Readiness combines overall accuracy, topic coverage, and best exam score. Treat it as a study indicator, not a guarantee of passing.

Electrical Calculators

Formula Guide

Ohm's law: I = V ÷ R, V = I × R, R = V ÷ I
Single-phase: VA = V × I
Three-phase: VA = 1.732 × V × I
Three-phase real power: W = 1.732 × V × I × PF
Voltage drop %: drop ÷ system voltage × 100
Continuous load: 125% continuous + 100% noncontinuous

Practice tools versus exam calculator

The electrical calculators below are study tools. During a simulated test, the on-screen calculator is intentionally limited to a conservative nonprogrammable standalone style. Wisconsin DSPS states that programmable calculators and cell-phone calculators are not allowed.

What counts as a lookup?

Home counter updates immediately

Opening a search result or answering a timed lookup drill counts toward today’s lookup goal. Typing in the search box by itself does not count.
