What is a diode? Describe the theory of diode operation. What is the application of it? What are the types of diode? List them and draw their symbol. Diode: When a p-type semiconductor and an n-type semiconductor are joined, the device is known as a diode. It has two terminals known as electrodes, one electrode each from p‐region and n‐region hence called diode (Di + … [Read more...] about What is a diode? What is the application of it?
