forward bias characteristics of a $LED$

Vedclass · Answer

(D) The graph shows current $I$ in $mA$ on the $y$-axis and voltage $V$ in $Volt$ on the $x$-axis in the first quadrant,indicating forward bias characteristics. Among the given options,a Light Emitting Diode $(LED)$ operates in forward bias,where the current increases exponentially with voltage after the threshold voltage is reached,leading to light emission due to the recombination of charge carriers. Therefore,the graph represents the forward bias characteristics of an $LED$.
