  1. What is the total resistance of two 10-ohm resistors connected in parallel?

    Answer: 5 ohms

    Equal parallel resistors give half the value, so 10/2 = 5 ohms.

  2. Which device protects a circuit by melting when current exceeds a rated value?

    Answer: Fuse

    A fuse contains a metal element that melts to open the circuit during overcurrent.

  3. In a purely resistive AC circuit, the voltage and current are:

    Answer: In phase

    Resistance does not shift phase, so voltage and current peak together.

  4. What unit measures electrical power?

    Answer: Watt

    Power is measured in watts, the product of volts and amperes.

  5. A step-down transformer has more turns on which winding?

    Answer: Primary

    A step-down transformer has more primary turns to lower the secondary voltage.

  6. What is the purpose of a grounding conductor?

    Answer: Provide a safe path for fault current

    Grounding gives fault current a low-resistance path to safely trip protection.

  7. Doubling the voltage across a fixed resistor will:

    Answer: Double the current

    By Ohm's law, current is proportional to voltage for a fixed resistance.
