A 20 ohm resistor and 20 ohm inductor are connected in series. What is the phase difference between the voltage and current?
Q1. A 20 ohm resistor and 20 ohm inductor are connected in series. What is the phase difference between the voltage and current?
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.
