Draw a circuit diagram with a p-n junction in forward bias.

Draw a circuit diagram with a p-n junction atreverse bias.

P-N junction is:

How does the junction width change when a p-n junction is forward biased?

Define Rectification. With the help a circuit diagram explain the working of p-n junction diode as a half wave rectifier.

Draw a circuit diagram to show how a photodiode is biased.
