Current lags behind the voltage by 90°
Current leads the voltage by 90°
Current can lead or lag the voltage by 90°
Current is in phase with the voltage
Answer is Right!
Answer is Wrong!
The correct answer is D. Current is in phase with the voltage in a pure resistive circuit.
In a pure resistive circuit, there is no inductance or capacitance, so the current and voltage are in phase. This means that the current and voltage waveforms reach their maximum and minimum values at the same time.
The other options are incorrect because they describe the relationship between current and voltage in a circuit with inductance or capacitance. In a circuit with inductance, the current lags the voltage by 90°. In a circuit with capacitance, the current leads the voltage by 90°.
