Question:
Draw a diagram showing resistance in an AC circuit and the voltage and current waveform.
Draw a diagram showing resistance in an AC circuit and the voltage and current waveform.
Show Hint
In a pure resistive AC circuit, voltage and current waveforms rise and fall together with zero phase difference.

Show Solution
Verified By Collegedunia
Solution and Explanation
The voltage and current are in phase with each other.
Both voltage and current waveforms are sinusoidal and peak at the same time.
The waveform of voltage (V) and current (I) overlap, indicating no phase difference. This means the current changes instantaneously with the voltage in a purely resistive circuit.
