Viva Questions pn Junction diode Characteristics
P-N Junction Diode
To draw the characteristics means behavior of current in forward and reverse bias of a semiconductor junction diode. This semiconductor diode either made by silicon or germanium which have atomic number Z=14 or Z=32 respectively. There are some questions related to this science experiment, these can help you to understand its working better.
