  1. Question 1

    Q1. A 10 Ω resistor and a 20 Ω resistor are connected in parallel. What is their equivalent resistance?

    • A) 10 Ω
    • B) 12.5 Ω
    • C) 20 Ω
    • D) 30 Ω

    Answer: 12.5 Ω

    Explanation: Using the formula 1/Rt = 1/R1 + 1/R2, we find the equivalent resistance. The other options are incorrect due to incorrect calculations or assumptions.
