Describe the phase relationship between current and voltage in a resistive circuit.

What will be an ideal response?


When an AC voltage is applied to the resistive load, the AC current's amplitude and direction vary in the same manner as those of the applied voltage. When the applied voltage changes polarity, the current also changes. They are said to be in phase. The current and voltage waveforms pass through zero and maximum values at the same time. However, the two waveforms do not have the same peak amplitudes because they represent different quantities, measured in different units.
