Questions & Step-by-Step Solutions
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.
