WHAT IS ELECTROSTATICS? : Introduction, Frictional Electricity, Kinds of Charges

WHAT IS ELECTROSTATICS? : Introduction, Frictional Electricity, Kinds of Charges

Let us know about electrostatics. Electrostatics is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges.

Then Let us know about frictional electricity. The substances which acquire charges on rubbing are said to be ‘electrified’ or charged. These terms are derived from the Greek word elektron, meaning amber.

The electricity produced by friction is called frictional electricity. If the charges in a body do not move, then, the frictional electricity is also known as Static Electricity.

Next we will deal with Two kinds of charges. They are positive and the negative charges. First of all a glass rod is rubbed with a silk cloth, it acquires positive Charge, while the silk cloth acquires an equal amount of negative charge. Secondly an ebonite rod is rubbed with fur, it becomes negatively charged, while the fur acquires equal amount of positive charge. This classification of two kinds of charges ie positive and negative charges were termed by American scientist, Benjamin Franklin.
