Under reverse bias, the diode ordinarily does not conduct (save a small dark current or I leakage).
Pinch-off occurs at a particular reverse bias (V) of the gate-source junction.
A photodiode is designed to operate in reverse bias.
This change in channel strength by application of reverse bias is called the body effect.
And like a diode, too much reverse bias can damage or destroy the valve assembly.
By applying a reverse bias, the vacancies diffuse back into the defective layer and the resistance returns to its original state.
The current density for the forward and reverse bias can calculated as follows:
That very small current is the source of the leakage current under reverse bias.
An electrolytic can withstand a reverse bias for a short period, but will conduct significant current and not act as a very good capacitor.
The reverse bias is shown when people explain others' success or failure.
