  1. Question 1

    Q1. A circuit with two resistors in series has a total resistance of 20 ohms. What is the current in the circuit if the voltage source is 10 V?

    • A) 0.5 A
    • B) 1 A
    • C) 2 A
    • D) 2/5 A

    Answer: 1 A

    Explanation: The current in the circuit can be found by using Ohm's law I = V/R.
