Ohm’s Law – Relationship between current and voltage

Ohm’s law is one of the basic principles of electricity. It relates the basic parameters of electricity, current and voltage, to each other. Georg Ohm, after whom the law was…

Conductance | What is conductance?

Every material in the universe is believed to be made up of atoms. In an atom, electrons are bound to its nucleus by a strong force of attraction by the…

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…

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…

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…

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…

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…
