Electricity

Electricity has an important role in modern society. 

It is of two types:

  • Static Electricity
  • (Current Electricity

STATIC ELECTRICITY:

A Physical phenomena produced due to charges at rest is known as static electricity.

Ex. When we rub a glass rod with silk the glass rod gets positive charge on it and equal and opposite charge (i.e. the -ve charge) gets developed on the silk. Similarly on a rubbing an ebonite rod with the fur of a cat the ebonite rod get negative charge on it and equal and opposite charge (i.e. the +ve charge) gets developed on the fur of a cat.

CURRENT ELECTRICITY:

A Physical phenomena produced due to charges in motion is known as current electricity. E.g. electric current we use in our houses is current electricity.
