So here we are talking about one more type of BJT amplifier, that is called Common Collector Amplifier. In this type of connection we give the input signal to the base pin of the transistor and then we take the output signal from the emitter pin. That means here the collector pin is working like […]

Class-A Amplifier Working Explained using Formulas
The common emitter class-A amplifier is specifically engineered to generate a significant output voltage swing even when it is fed with a relatively minuscule input signal voltage that might only be a few millivolts. These amplifiers are primarily utilized as what we call “small signal amplifiers” a concept we explored in our earlier tutorials. Now […]
Common Emitter Amplifier Circuit: Explained with Formulas
Basically when we talk about transistor amplifiers, they are designed to work with AC input signals that goes up and down between a positive value and a negative values. Now to make sure that the transistor can work properly between these two extreme points, we need to set things up in a specific way. This […]
Transformer Voltage Regulation: Explained with Formulas
When we talk about voltage regulation we are looking at how good a transformer is at keeping its secondary voltage steady even when the load changes. Sometimes the output voltage we get from the secondary side is not exactly what we were expecting and that is where voltage regulation comes into play. Now when you […]
Electrical Transformer Working: Explained with Formulas
In this tutorial about transformers I will explain the basics in simple terms. As we know transformers can work without any moving parts inside and it is mainly used to change voltage levels so that we can transfer energy from one circuit to another through electromagnetic induction. We use alternating current (AC) in our homes […]
Understanding FET Current Source: Explained with Formulas
An FET Current Source is a specific kind of active circuit which employs a Field Effect Transistor to provide a steady and a constant amount of current to a circuit. Now you might wonder why it is important for us to have a constant current. Constant current sources and their opposite, which we call current […]
