In light emitting diode (LED), light is given out due to
1 emission of holes and electrons
2 recombination of holes and electrons
3 diffusion of holes
4 drifting of electrons
Explanation:
B In light emitting diode (LED), light is given out due to recombination of holes and electrons. An LED is a p-n junction diode in which light emits in the forward biased.
