  1. What is the purpose of electrical grounding in a utility system?

    Answer: Provide a safe path for fault current

    Grounding provides a low-resistance path for fault current to flow safely to earth, protecting equipment and personnel.

  2. Which device is used to measure current in a live circuit without disconnecting wires?

    Answer: Clamp meter (clamp-on ammeter)

    A clamp meter measures current by clamping around a conductor without breaking the circuit.

  3. What does 'GFCI' stand for in electrical work?

    Answer: Ground Fault Circuit Interrupter

    GFCI stands for Ground Fault Circuit Interrupter, a safety device that interrupts circuits on detecting small ground faults.

  4. In AC power systems, what does 'power factor' measure?

    Answer: Efficiency of real power use vs. apparent power

    Power factor is the ratio of real power (watts) to apparent power (VA), indicating how efficiently power is used.

  5. What is the purpose of a neutral conductor in a standard 120V circuit?

    Answer: Provide a return path for current to the source

    The neutral conductor completes the circuit by carrying return current back to the power source.

  6. Which statement best describes a short circuit?

    Answer: An unintended low-resistance path causing excessive current

    A short circuit is an accidental low-resistance connection that allows abnormally high current to flow.
