Vedclass · Answer

(A) In an $LED$,the intensity of emitted light depends on the number of charge carriers crossing the junction. As the forward bias voltage increases from zero,the potential barrier decreases,allowing more electrons and holes to cross the junction and recombine. This recombination releases energy in the form of photons,thus increasing the intensity of the emitted light. Therefore,the intensity increases with the applied forward bias.

In an $LED$,when forward bias is increased (starting from zero),the intensity of emitted light will:
