The cause of the potential barrier in a PN diode is ______?

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.
