FE Electrical and Computer practice questions with worked solutions
FE Electrical and Computer questions reward clean separation of circuit, signal, power, control, and computing models. Practice identifying the domain first, then use the handbook to verify equations and conventions.
Try an original Electrical & Computer question
Choose an answer before reviewing the solution. Pay attention to the governing model and setup, not only the final choice.
A 120 V rms source is connected across a 30 ohm resistor. The average power absorbed by the resistor is most nearly:
A better review loop for FE Electrical and Computer
Practice creates useful evidence only when the review explains why the setup worked or failed. Use this three-part loop after every question.
Name the domain
Decide whether the problem is a circuit, signal, power, controls, digital, or computing question before calculating.
Track reference and phase
Write polarity, current direction, RMS or peak convention, and phase reference before using a formula.
Test the limiting case
Check DC, high-frequency, zero-input, or steady-state behavior when the result is uncertain.
