^ Terms associated with a rectifier Output current in load for one complete cycle

Let Input voltage V = V_o sin ωt is applied to a rectifier, then

For a half wave rectifier

Let r_f & R_L are the forward resistance of the junction and the load resistance respectively

Then peak value of output current will be

For a full wave rectifier

The negative sign indicates that the current due to the second diode flows through the circuit a time T/2 later than the current due to the first diode.
