What is Potentiometer : Working & Its Applications
Potentiometers are variable resistors that were first invented to amplify radio signals. You could find it in an old radio or a stereo system as a volume control. Earlier it was named 'multiplier' by Charles William Siemens and but nowadays it is commonly called 'POT'. It is used today in both electrical and physical applications and is an integral part of electronic circuits, motor controls, and many other areas. In this article let's look into different types of the potentiometer, its … [Read more...]

Types of Resistors & Their Applications
A resistor is one kind of passive component used to obstruct the current flow within electrical and electronic circuits. There are different types of resistors available in the market which are used based on the requirement. The best examples of resistive materials are Mica, Glass, Rubber, Wood, etc. The unit of resistance is ohm where 1 ohm = 1V/1A. And also, these components play a key role in electronic circuits like signal levels can be adjusted, current flow can be reduced, divide … [Read more...]
What is a Resistor Color Code & Its Calculation
Resistors are small electrical components, used in several electrical and electronic circuits to restrict the flow of current within the circuit and also to regenerate voltage drop in several ways. These are available in different sizes and shapes. Each resistor includes a resistance or resistive value that ranges from ohms to milliohms. So these values can be measured through the color band concept. For each small component, a color code is used to indicate the resistance value instead of … [Read more...]

What is RL Circuit : Derivation & Its Phasor Diagram
In basic electronics, the circuits are divided into various categories based on the operation, structure, connection, etc. The electronics circuits are active, passive, analog, digital, and mixed-signal circuits. Consider a passive circuit with passive elements like resistor, capacitor, and inductor which are combined to form 4 types of circuits such as RL circuit, RC circuit, LC circuit, and RLC circuit. These passive elements in the passive circuit don’t generate power but store the energy. … [Read more...]
What is Carbon Composition Resistor & Its Working
In electronic circuits, resistors are the passive two-terminal devices used to regulate or reduce the flow of current in the circuit. Mostly fixed type resistors are used in the electronic circuits because of its fixed resistance value. The resistance is determined during the manufacturing process itself and it can't be varied like a variable type resistor. Based on the manufacturing process, the fixed type resistors are divided into 4 types such as carbon resistors, wire wound resistors, … [Read more...]
