  1. What is the frequency of standard AC power in the United States?

    Answer: 60 Hz

    Standard US line power alternates at 60 cycles per second.

  2. What component stores energy in an electric field?

    Answer: Capacitor

    A capacitor stores charge as energy in an electric field between plates.

  3. Ohm's law states that voltage equals current multiplied by what?

    Answer: Resistance

    Ohm's law is V = I × R.

  4. What does a multimeter set to the continuity setting tell you?

    Answer: Whether a complete path exists between two points

    Continuity confirms a low-resistance connected path, often with a beep.

  5. Which type of motor is most commonly used for large industrial AC applications?

    Answer: Three-phase induction motor

    Three-phase induction motors are rugged and efficient for industrial loads.

  6. What unit measures electric current?

    Answer: Ampere

    Current is measured in amperes (amps).

  7. Why is a higher gauge number on a wire significant?

    Answer: It indicates a thinner wire
