Question:medium
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.
Updated On: Jan 14, 2026
Show Solution
Solution and Explanation
Voltage and current are synchronized.
Both voltage and current exhibit sinusoidal patterns and reach their maximum values simultaneously.
The graphical representations of voltage (V) and current (I) coincide, signifying no phase displacement. This implies that in a purely resistive circuit, current reacts immediately to changes in voltage.
