Resistor in ac circuit alternating current has alternating source of emf. In dc the voltage and current. The resistor is the passive device which neither produce nor consume electric power.
Let an alternating source of emf be connected across a resistor of resistance r.
An ac generator or ac dynamo can be used as an ac voltage source. In direct current dc the flow of electric charge is unidirectional. The instantaneous value of the applied emf is. An ac generator or ac dynamo can be used as an ac voltage source.
