Use of Transistor as a Switch | switching circuit

A switch or key is useful to ON or OFF the circuit connection to activate or deactivate a device. For example, if we want to ON or OFF a fan or a TV or a Tube light we need to press on switches. Sometimes, in physics laboratory we use tapping key to connect the circuit … Read more

What is Bipolar Junction Transistor BJT?

Bipolar Junction Transistor (BJT) is one of the very important electronic circuit components in the world of electronics. Scientist William Shockley discovered the first Transistor in 1948. In modern days, technology is better and many variety of transistor have been discovered. In this article, we are going to discuss what is Bipolar Junction Transistor (BJT)? … Read more

Difference between NPN and PNP Transistor in tabular form

Transistor is one of the basic circuit components for electronic operations. The main purpose of a Transistor is to Amplify electronic signals at the output of a circuit. We already know that there are two types of Transistors – NPN and PNP transistor. An NPN Transistor can be formed by sandwiching p-type material or acceptor … Read more
