(i) No current flows in the junction diode without an external battery. It is connected to a battery in two different ways. Hence two different bias are possible in junction diode.

(a) Forward bias            
(b) Reverse bias

S.No.Forward biasReverse bias
1.

The P-region of Junction diode Is connected to positive terminal of battery and N-region is connected to negative terminal of battery.

3.

Current flows in it due to majority electrons and majority holes and hence high current (mA) flows in it.

Forward and Reverse Biasing Class 12 Notes | EduRev

The direction of current in it is from P to N.

Current flows in it due to minority electrons and minority holes and hence negligible current (in μA) flows in it.
