  1. Question 1

    Q1. A 100 ohm resistor and 100 ohm inductor are connected in series. What is the phase difference between the voltage and current?

    • A) 0 degrees
    • B) 45 degrees
    • C) 90 degrees
    • D) 180 degrees

    Answer: 90 degrees

    Explanation: The correct answer is C because the phase difference between the voltage and current in a series R-L circuit is determined by the inductive reactance.
