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

Options:

Correct Answer: 0 degrees

Solution:

In a purely resistive load, the voltage and current are in phase, meaning the phase difference is 0 degrees.

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

Correct Answer: 0 degrees

Step 1: Understand what an AC circuit is. AC stands for alternating current, where the current and voltage change direction periodically.
Step 2: Know what a purely resistive load is. A purely resistive load means that the circuit only has 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 in the circuit.
Step 4: In a purely resistive load, 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 load, the voltage and current reach their maximum and minimum values simultaneously, resulting in a phase difference of 0 degrees.
