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

Options:

Correct Answer: 0 degrees

Solution:

In a purely resistive circuit, the voltage and current are in phase, resulting in a phase difference of 0 degrees.

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

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

Step 1: Understand what an AC circuit is. An AC circuit is one where the current alternates direction periodically.
Step 2: Know what a purely resistive circuit means. A purely resistive circuit has only resistors and no capacitors or inductors.
Step 3: Learn about phase difference. Phase difference refers to the difference in timing between the voltage and current waveforms.
Step 4: In a purely resistive circuit, the voltage and current reach their maximum and minimum values at the same time.
Step 5: Since the voltage and current are at their peaks together, they are said to be 'in phase'.
Step 6: When two waveforms are in phase, the phase difference is 0 degrees.

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