  1. What does a multimeter set to the ohms range measure?

    Answer: Resistance

    The ohms setting measures resistance in a component or circuit.

  2. Three 6-ohm resistors are connected in series. What is the total resistance?

    Answer: 18 ohms

    Series resistances add, so 6 + 6 + 6 = 18 ohms.

  3. Which color is typically used for the equipment grounding conductor in US wiring?

    Answer: Green

    Green or bare wire is the standard US equipment grounding conductor.

  4. What component stores energy in an electric field?

    Answer: Capacitor

    A capacitor stores energy in the electric field between its plates.

  5. A motor that fails to start but hums is most likely missing:

    Answer: A starting capacitor or phase

    A humming motor that won't start often lacks starting torque from a bad capacitor or lost phase.

  6. What is the frequency of standard US residential AC power?

    Answer: 60 Hz

    Standard US residential power operates at 60 hertz.

  7. Which instrument measures current without breaking the circuit?

    Answer: Clamp meter

    A clamp meter senses the magnetic field around a conductor to read current.
