  1. Question 1

    Q1. A circuit with two resistors in series has a total resistance of 30 ohms. If the voltage of the voltage source is 10 V, what is the current in the circuit?

    • A) 0.33 A
    • B) 0.5 A
    • C) 0.67 A
    • D) 10/6 A

    Answer: 0.67 A

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