Sample Questions on Rectifier
Question 1: What happens to the width if the depletion layer of a P-N junction when it is forward biased and reverse biased?
Answer:
- Width of the depletion layer decreases in forward bias.
- Width of the depletion layer increases in reverse bias.
Question 2: What is the most common use of photo diode?
Answer:
It is used as a photodetector to detect optical signals.
Question 3: What type of impurity is added to obtain n-type semiconductor?
Answer:
Pentavalent atoms like phosphorus(P) and arsenic (As).
Rectifier
Rectifier is an electronic component that converts alternating current (AC) into direct current (DC), ensuring a unidirectional flow of electric charge. As we know, electricity reaches our homes from power grids in the form of AC, but most commonly used electric appliances, such as mobile phones, computers, televisions, fridges, etc operate on direct current (DC). Therefore, the rectifier becomes a very useful component in electronics.
This article provides a detailed understanding of the electrical component known as a rectifier, including its types such as full-wave and half-wave rectifiers, controlled and uncontrolled rectifiers, etc. In addition to that, we will learn about various specific rectifiers such as the Mercury Arc Rectifier, Selenium Rectifier, and Precision Rectifiers.
