Graph $(b)$

Vedclass · Answer

(B) An $LED$ (Light Emitting Diode) is a heavily doped $p-n$ junction diode that emits light when biased in the forward direction.Its $I-V$ characteristics are similar to those of a standard $p-n$ junction diode.In the forward bias region,the current increases exponentially with the applied voltage after the threshold (knee) voltage is reached.In the reverse bias region,the current is negligible.Graph $(a)$ represents a standard $p-n$ junction diode characteristic.Graph $(b)$ shows a forward bias characteristic starting from the origin,which is the standard representation for an $LED$ in the first quadrant.Therefore,graph $(b)$ is the correct representation.

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