In an electric circuit, when two or more electric circuit components are joined together in such a way that there is only one path for the flow of electric current, such connection of circuit components is referred to as series circuits. Therefore, in a series circuit, the current through all ... Read More

An electronic circuit in which the output voltage follows the input voltage is known as a voltage follower. In other words, a voltage follower is an electronic circuit whose output voltage remains the same as the input voltage. We can design a voltage follower using an operational amplifier. A voltage ...

In this article, we will discuss the uninterruptible power supply (UPS), its block diagram, types, and applications. So, lets’ begin with the basic definition of the uninterrupted power supply (UPS). What is a UPS? UPS stands for Uninterruptible Power Supply. An Uninterruptible Power Supply (UPS) is an electrical device used ... Read More

A voltage regulator is an electronic circuit which is used to control the variations in the output voltage of a power supply so that it will remain within the suitable limits. Since, in the case of practical circuits, the voltage changes due to several reasons such as change in input ... Read More

The electrical and electronic components such as resistors, capacitors, inductors, wires, cables, insulators, etc. are made up of different types of material. We generally refer all these materials as engineering materials. Based on electrical resistivity, the engineering materials are categorized into three categories namely – conductors, semiconductors, and insulators. Since ... Read More

A parameter of an oscillatory system, such as an ac circuit, which expresses the relationship between stored energy and energy dissipation is known as quality factor of the system. The quality factor is also called as Q-factor. Mathematically, the quality factor or Q-factor of an ac circuit is given by ... Read More

In electrical and electronic circuits, some components are used to supply the required electrical energy for the operation of the circuit. These components are known as energy sources. Energy sources are the active circuit elements that can supply the necessary excitation, i.e. required electrical energy, to the circuit. In practice, ... Read More

In electrical and electronic circuits, resistance or electrical resistance is defined as the amount of friction in the flow of electric current (or electric charge) offered by the conductor material. The electric circuit element that is used to introduce the electrical resistance in the circuit is called resistor. The resistor ... Read More

In this article, we will discuss the factors affecting the resistance of a conductor and the change in the resistance of a substance with the variation in temperature. Let’s begin with a basic introduction of electrical resistance. Electrical resistance is defined as the measure of opposition that a material offers ... Read More

A capacitor is an electronic circuit component that stores electrical energy in the form of electrostatic charge. Thus, a capacitor stores the potential energy in it. This stored electrical energy can be obtained when required. Ideally, a capacitor does not dissipate energy, but stores it. A typical capacitor consists of ... Read More
