Question

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.

Answer 1

Depletion layer is formed when immobile charges left across the junction during the movement of majority charges in opposite side

Half wave rectifier rectifies the negative potential of the wave and we get only half wave for one single wave

Explanation:

• In p-n junction majority charge carriers tends to move in opposite side for example electrons move towards p type semiconductors and holes move towards n type semiconductor and they left behind the immobile charge carriers this layer formed by immobile charge carriers is known as depletion layer
• An imaginary battery is set up across the junction is known as barrier potential
• Half wave rectifier consist of a p-n junction diode which acts like short circuit when it is forward bias thus offers very little resistance and acts like open circuit when it is reversed bias so offers very large distance hence blocks the output wave in reverse bias during every cycle
• Circuit diagram of half wave rectifier is attached below
