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 switches. Sometimes, in physics laboratory we use tapping key to connect the circuit to … Read more
We know that a Transistor can amplify the electric current at its output. Often, the amount of the amplified output does not meet the required criteria. That means we need the output current more than that. Then scientist Darlington proposed a new circuit arrangement with two coupled transistors which provides a huge current gain. This … Read more
In another article, we have discussed the Bipolar Junction Transistor and the differences between NPN and PNP transistors. Transistor characteristic curve is a very useful thing to understand the basic principle and operation of a Transistor. In this article, we’re going to discuss the input and output characteristics of a Transistor. The main discussion is … Read more
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. Modern technology is very much progressive and many varieties of transistors have been discovered. These transistors are widely used in analog and digital electronics. In short, semiconductor diodes … Read more
Transistor is one of the basic circuit components for electronic devices. The main purpose of a Transistor is to Amplify electronic signals. There are two types of BJT Transistors – NPN and PNP. In another article, we discussed the construction, symbol and other properties of BJT Transistors. In this article, we’re going to discuss the … Read more
