1 Answer

Answer :

i)P-N junction diode: It is a semiconductor device in which half of its region is P-type and other half is N-type. 

ii) Depletion layer: The region where free electrons and free holes are absent is called depletion layer. 

iii) Forward bias: If the positive terminal of external battery is connected to p – side and negative terminal is connected to n-side of p-n junction diode, it is said to be forward bias. 

iv) Reverse bias of P-N junction diode: If the positive terminal of external battery is connected to n – side and negative terminal is connected to p-side of p-n junction diode, it is said to be reverse bias.
