Question: In a purely resistive AC circuit, what is the phase difference between voltage and current?

Options:

Correct Answer: 0 degrees

Solution:

In a purely resistive AC circuit, the voltage and current are in phase, meaning there is a phase difference of 0 degrees.

In a purely resistive AC circuit, what is the phase difference between voltage and current?

In a purely resistive AC circuit, what is the phase difference between voltage and current?

Step 1: Understand what a purely resistive AC circuit is. It means the circuit only has resistors and no capacitors or inductors.
Step 2: Know that in an AC circuit, voltage and current can be out of phase, which means they can reach their maximum and minimum values at different times.
Step 3: In a purely resistive circuit, the voltage and current reach their maximum and minimum values at the same time.
Step 4: Since they reach their maximum and minimum values together, this means they are in phase.
Step 5: When two waveforms are in phase, the phase difference between them is 0 degrees.

Phase Difference in AC Circuits – In a purely resistive AC circuit, voltage and current reach their maximum and minimum values at the same time, resulting in a phase difference of 0 degrees.
