Thank You,sir... It helped alot... and even both books of physics (Concepts of Physics 1 & 2 by H.C.Verma) H.C.Verma sir is my favourite one... I like his method of teaching...
Yeahh! It was fun learning with you. This portion was seemingly very tough for me but you helped me grasp the concept so well that now fear is gone. It was amazing... Thank you so much
Current is always present in reverse bias although very small, because of minority charge carriers. But in zener diode the current increases manifold suddenly due to increase in applied voltage upto a certain threshold.
