What is the difference between forward and reverse bias?
What is the difference between forward and reverse bias?
Last answer:
Forward bias is a PN junction bias which allows current to flow through the junction. Forward bias decreases the resistance of the depletion layer. Reverse bias is a PN junction bias that allows only ... Positive polarity on the n-type material and negative polarity to the p-type material.
