## Capacitance| What is a capacitor?

The device that offers pure capacitance is known as a capacitor. A capacitor is a two-terminal energy storage device, that stores energy in its electric field. It can be found in turning and filtering circuits. It consists of two metallic plates facing each other and separated by a dielectric medium such as air, ceramic, mica … Read more

## Inductance | What is an inductor?

Inductance A conductor carrying current produces a magnetic field around it. This magnetic field follows a circular path. When the same conductor is wound over a cylindrical solid core, the magnetic field formed around it amplifies. Any change in the rate of current flow through this conductor causes a change in the magnetic field, thereby … Read more

## What is Electric Power?

Before reading about electric power it is essential to have a basic idea about power. The word power is a little tricky to understand. Consider that you are riding a bicycle at a speed of 20km/hr for an hour. A certain amount of work is done by you here. The amount of work done by … Read more

## What is energy?

Energy can be defined as the capacity to do work. It can also be defined as “stored work”. The terms energy and power are confusing and are interchanged most of the times. Consider that you are riding a bicycle at a speed of 20km/hr for an hour. A certain amount of work is done by … Read more

## What is Resistance?

As we know the current is the flow of free electrons through material from a higher potential to a lower potential. During this flow, few of these electrons collide with other atoms in the material and lose their energy in the form of heat. These collisions cause a drop in potential across the material. This … Read more

## Electric Current and Current Flow

To understand the basics of electricity it is necessary to understand the concepts of electric charge and current. Electrically charged particles are present in every matter in the universe. The unique property of these charged particles is that it can move on the application of an external force. This article aims to help you understand … Read more

## Electric Charge

Like gravitational force that acts on all masses, the electrostatic force is another fundamental force in nature. The term ‘electric charge’ is very difficult to explain but we can describe its properties. All particles present in nature are composed of charges. The history of charges extends back to 200BC. If you want to experience charge, … Read more

## Difference between neutral and earth / ground

This article focus on explaining the similarities and dissimilarities between neutral and earth (ground). Understanding the difference between neutral and earth may be difficult in the beginning. A Lot of safety and protection-related aspects need to be carefully studied for a better understanding of the difference between them. Note: For this article, let us consider … Read more
