  1. What is the primary purpose of a fuse in an electrical circuit?

    Answer: Protect against overcurrent

    A fuse melts and opens the circuit when current exceeds a safe level, protecting components.

  2. If a circuit has 12V across a 4-ohm resistor, how much power is dissipated?

    Answer: 36 watts

    P = V²/R = 12²/4 = 144/4 = 36 watts.

  3. What does the term 'frequency' refer to in AC circuits?

    Answer: The number of complete cycles per second

    Frequency is measured in hertz (Hz) and indicates how many complete cycles occur each second.

  4. What type of circuit has only one path for current to flow?

    Answer: Series circuit

    In a series circuit, all components share the same single current path.

  5. What is the function of an inductor in an AC circuit?

    Answer: Opposes changes in current

    An inductor opposes changes in current due to its self-induced back-EMF (inductive reactance).

  6. Which material is considered a semiconductor?

    Answer: Silicon

    Silicon is a classic semiconductor used in transistors, diodes, and integrated circuits.

  7. In electrical wiring, what does AWG stand for?

    Answer: American Wire Gauge

    AWG stands for American Wire Gauge, a standardized system for wire diameter sizes.
