why does p side and n side of p-n junction are heavily doped in zener diode? why zener diode connected in reverse bias not forward biased?? what is the function of load resistance in zener diode?

Expert Answer:

Zener diode is used in reverse biasing because in breakdown region the current changes many folds with a negligble change in voltage.sO That it could be used as a voltage regulator and we can take output voltage through load resistance .
