  1. Question 1

    Q1. A battery of internal resistance 5Ω is connected in parallel with a 10Ω resistor. What is the total resistance of the circuit?

    • A) 5Ω
    • B) 10Ω
    • C) 12Ω
    • D) 15Ω

    Answer: 12Ω

    Explanation: Parallel resistors do not add to total resistance; instead, they short circuit.
