Question:easy

Which of the following statement is NOT correct in the case of LED?
(A) It is a heavily doped p-n junction diode.
(B) It emits light only when it is forward biased.
(C) It emits light only when it is reverse biased.
(D) The energy of the light emitted is equal to or slightly less than the energy gap of the semiconductor used.

Show Hint

An LED emits light only under forward bias.

  • A
  • B
  • C
  • D
Show Solution

The Correct Option is C

Solution and Explanation

Step 1: Biasing
Under reverse bias hardly any current flows through an LED, so no recombination and no light. Therefore statement (C) is the incorrect one.

Final Answer:
Statement C. \[ \boxed{\text{(C)}\ \text{(C)}} \]
