What is Diode ?

A diode is mainly made from small piece of semi conductor material usually silicon ,characterized as a two-terminal electronic segment that solitary behaviors current one way (insofar as it is worked inside a predetermined voltage level). A perfect diode will have zero obstruction one way, and interminable opposition in the converse heading.

Despite the fact that in reality, diodes can not accomplish zero or unending opposition. Rather, a diode will have irrelevant obstruction one way (to permit current stream), and exceptionally high opposition in the converse bearing (to forestall current stream). A diode is successfully similar to a valve for an electrical circuit.
