Question

The light emitting diode (LED) is

• A. a heavily doped p-n junction with no external bias
• B. a heavily doped p-n junction with reverse bias
• C. a heavily doped p-n junction with forward bias
• D. a lightly doped p-n junction with no external bias
• E. a lightly doped p-n junction with reverse bias

Hint:

Remember that LEDs convert electrical energy directly into light. They are always used in forward bias to allow the recombination process that produces photons.

Answer 1

The Correct Option is C
