  1. Question 1

    Q1. A circuit with two resistors in series has a total resistance of 20 ohms. If the current in the circuit is 2 A, what is the voltage of the voltage source?

    • A) 40 V
    • B) 20 V
    • C) 10 V
    • D) 10/2 V

    Answer: 40 V

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