  1. Question 1

    Q1. A circuit with two resistors in series has a total resistance of 25 ohms. If the current in the circuit is 1 A, what is the voltage of the voltage source?

    • A) 25 V
    • B) 20 V
    • C) 15 V
    • D) 5 V

    Answer: 25 V

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