Diodes allow electricity to only flow in one direction, thus converting alternating current (a.c.) into direct current (d.c.). They also allow electrons to flow one way only (until reverse breakdown occurs - then current may flow in both directions).
Diodes are often used in both domestic and industrial applications and they are especially useful in electrical circuits.

∙ 11y agoA diode works in a simple fashion. It has a p-n junction, which is nothing more then two slightly different types of material pressed together. This allows electricity to flow with very little resistance in one direction, called the diode's forward direction, but with very high resistance in the other direction.
This process is called rectification. It is useful in converting Alternating Current to Direct Current.

In a circuit that can have electricity try to go both ways, a diode allows only one.

What is the Principle and operation characteristic of switching diode?
A: The principle is that is a semiconductor meaning will conduct one way only. A switching diode however will have the least of capacitance across its junction so when it disconnect is faster

What is working principle?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
