  1. Question 1

    Q1. A 10-V potential difference exists between points A and B in a circuit. A 5-ohm resistor is connected between points A and C. What is the potential difference between points A and C?

    • A) 10 V
    • B) 5 V
    • C) 0 V
    • D) 15 V

    Answer: 0 V

    Explanation: The potential difference is proportional to the resistance, making 0 V a plausible but incorrect answer.
