PN junction

Which of the following current must be zero in an unbiased P.N. junction diode ?

The contact potential at the junction site in a P-N junction is-

When the voltage drop across a p.n junction diode is increased from 0.65V to 0.70V , the change in the diode current is 5mA . What is the dynamic resistance of the diode?

The cell junctions like tight junctions, desmosomes and gap junctions are found in :

In a p-n junction , numbers of junction are

At any junction, the sum of the currents entering the junction is ...A.„ to the sum of currents leaving the junction. Here, A refers to
