  1. Question 1

    Q1. A 10 Ω resistor and a 20 Ω resistor are connected in parallel with a 5 Ω resistor. What is the equivalent resistance?

    • A) 5.0 Ω
    • B) 10.0 Ω
    • C) 15.0 Ω
    • D) 20.0 Ω

    Answer: 15.0 Ω

    Explanation: Using the formula 1/Rt = 1/R1 + 1/R2 + 1/R3, we find the equivalent resistance. The other options are incorrect due to incorrect calculations or assumptions.
