In a circuit containing only resistance, how does the current relate to the voltage?

Show Answers

The current lags the voltage by 90 degreesThe current leads the voltage by 90 degreesThe current either leads or lags the voltage by 90 degreesThe current and voltage are perfectly synchronized in phaseNo current flows in the circuit

Explanation

In a purely resistive circuit, the current and voltage waveforms align perfectly, meaning they are in phase with each other. Unlike inductive or capacitive circuits where current leads or lags voltage by 90 degrees, resistance causes no phase difference.
