Vedclass · Answer

(B) An $LED$ (Light Emitting Diode) is a $p-n$ junction diode that emits light when it is forward-biased. Therefore,its $V-I$ characteristics are similar to those of a standard $p-n$ junction diode operating in the forward bias region. In the forward bias region,the current increases exponentially with the applied voltage after the threshold voltage (knee voltage) is reached. Graph $(b)$ represents this exponential increase in current with voltage in the first quadrant,which is the characteristic behavior of an $LED$ in forward bias. Graph $(a)$ shows both forward and reverse bias,which is for a general diode. Graph $(c)$ represents the characteristics of a solar cell. Graph $(d)$ represents the characteristics of a photodiode.

The $V-I$ characteristics of an $LED$ are correctly shown by which graph?
