LED is a p-n junction diode which is

A

forward biased

B

either forward biased or reverse biased

C

reverse biased

D

neither forward biased nor reverse biased

Text Solution

Verified by Experts

The correct Answer is:
A
When a junction diode is forward biased , energy is released at the junction due to recombination of electrons and holes . In the junction diode made of gallium arsenide or indium phosphide , the energy is released in visible region . Such a junction diode is called a light emitting diode or LED.
