Semiconductor P-N Diode | P-N Junction

Semiconductor P-N Junction Diode Working Principle Diode is the two terminal  polarised electronic semiconductor device . One terminal is Anode(-) and other is Cathode(+). The cathode is marked with the silver colour or colour band. This is the simplest semiconductor device but this is very important and most useful in electronic circuits.   The main function of the semiconductor diode […]
