Question
Explain dynamic resistance of a diode.
✓
Answer
$1.$ The dynamic $(AC)$ resistance of a diode, $r_g,$ at a particular applied voltage, is defined as $r _{ g }=\frac{\Delta V}{\Delta I}$
$2.$ The dynamic resistance of a diode depends on the operating voltage.
$3.$ It is the reciprocal of the slope of the characteristics at that point.
