  1. Question 1

    Q1. A circuit with two identical resistors in parallel has a total resistance of 5 ohms. If the current in the circuit is 4 A, what is the voltage of the voltage source?

    • A) 20 V
    • B) 10 V
    • C) 5 V
    • D) 1 V

    Answer: 20 V

    Explanation: The voltage of the voltage source can be found by using Ohm's law V = I*R.
