(i) Name two important processes that occur during the formation of a pn junction.
(ii) Draw the circuit diagram of a full wave rectifier along with the input and output waveforms. Briefly explain how the output voltage/current is unidirectional.
(i) a) Drift
b) Diffusion
(ii)
During the positive and negative half cycle of the input waveform, the output is on the positive side. That is output are undirectional.
