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.
