  1. What does Ohm's Law state?

    Answer: Voltage equals current multiplied by resistance

    Ohm's Law states V = I × R (Voltage = Current × Resistance).

  2. In a series circuit with three resistors, how does removing one resistor affect total resistance?

    Answer: Total resistance decreases

    In a series circuit, total resistance is the sum of all resistors; removing one reduces the total.

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

    Answer: Protect against overcurrent by breaking the circuit

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

  4. Which type of current flows in one direction only?

    Answer: DC (Direct Current)

    DC (Direct Current) flows in one constant direction, unlike AC which alternates direction.

  5. What happens to current in a parallel circuit when one branch is opened (disconnected)?

    Answer: Current in other branches is unaffected

    In a parallel circuit, each branch operates independently; opening one branch does not interrupt others.

  6. The standard US residential voltage is approximately:

    Answer: 120 V

    Standard US residential outlet voltage is approximately 120 V AC for most outlets.
