Question

A light emitting diode is

• A. a n-p-n type semiconductor with a forward bias
• B. a p-n-p semiconductor with a reverse bias
• C. a p-n-p semiconductor with a forward bias
• D. a p-n semiconductor with a reverse bias
• E. a p-n semiconductor with a forward bias

Answer 1

Answer: (E)

Light emitting diode $(LED)$ is a heavily doped p-n junction diode. It emits spontaneous radiation, under forward bias
