As electron hole pair (because of thermal collisions) is continuously formed in the depletion region. These are a regular flow of electrons in the direction of the N-side and of holes in the direction of the P-side. This makes a current from the N-side to the P-side. This current is called as the drift current (idr).
why CPH has speed Vc and Vc is greater than c? Answer; since you know photon has spin. Thus the path per time of a point on photon is greater than c it means the speed of photo
Current flowing in a certain PN junction at room temperature is 2 X 10 -7 A, when a large reverse bias voltage is applied. Calculate current when a forward voltage of 0.1 V is appl
