Explain the formation of depletion layer and potential barrier in p-n junction.
Draw the circuit diagram of a half wave rectifier and explain its working.

Draw the circuit diagram of a half wave rectifier. Hence explain its working.

Explain the term depletion region and potential barrier for a p-n junction.

(a) Define the terms deplection layer and barrier potintial for a p-n jucntion (i) an increase in the doping concentration and (ii) biasing across the junction affect the width of the depletion layer (b) Draw the cirucit diagram of a p-n diode used a s a half wave rectifier explain its working

In the middle of the depletion layer of a reverse - biased p - n junction , the
