Electrical Power is the basis of modern life. It forms the basis for industrial and infrastructure developments and makes our life more comfortable. Today, most of the power we use…
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…
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…
The basic capacitive device is 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…
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…
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…
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…
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…
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…
Like gravitational force that acts on all masses, the electrostatic force is another fundamental force in nature. The term ‘charge’ is very difficult to explain but we can describe its…
