  1. Question 1

    Q1. A circuit has a net resistance of 12 ohms when a 3-ohm resistor is connected in series. What is the net resistance when a 2-ohm resistor is connected in series?

    • A) 10 ohms
    • B) 14 ohms
    • C) 15 ohms
    • D) 16 ohms

    Answer: 14 ohms

    Explanation: The net resistance is the sum of the individual resistances, making 14 ohms a plausible but incorrect answer.
