  1. Question 1

    Q1. A circuit has a total current of 5A and a potential difference of 20V. What is the total resistance of the circuit?

    • A) 2Ω
    • B) 4Ω
    • C) 6Ω
    • D) 8Ω

    Answer: 4Ω

    Explanation: Resistance is directly proportional to potential difference and inversely proportional to current.
