پی این ڈایڈڈ میں ممکنہ رکاوٹ کی وجہ ______ ہے؟
Explanation
The potential barrier in a PN diode is caused by the depletion region, where mobile positive and negative charges near the junction diffuse and leave behind immobile ions.
This depletion creates an electric field that opposes further charge movement, forming the potential barrier.
