Junction Rule

In a p-n junction diode, if the junction current is zero, it means that

Dynamic Resistance Of The Junction Node

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

In a p-n junction , numbers of junction are

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

you have three identical pn junction, junction 1 is unbiased, junction 2 is reverse biased and junction 3 is forward biased. From largest to smallest, rank the three junction according to the magnitude of their diffusion currents.
