  1. Question 1

    Q1. A circuit consists of a 10 Ω resistor in parallel with a 20 Ω resistor. If a current of 2 A flows through the 10 Ω resistor, what is the voltage across the 20 Ω resistor?

    • A) 10 V
    • B) 15 V
    • C) 20 V
    • D) 25 V

    Answer: 20 V

    Explanation: Using the formula V = IR, we find the voltage across the 20 Ω resistor. The other options are incorrect due to incorrect calculations or assumptions.
