What is drift current, Physics

Assignment Help:

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).
