Discuss the phenomena experienced due to electrostatics.

Explanation

All of us have the experience of seeing a spark or hearing a crackle when we take off our synthetic clothes or sweater, particularly in dry weather, and also with ladies garments like a polyester saree.
Another common example is the lightning that we see in the sky during thunderstorms.
We also experience a sensation of an electric shock either while opening the door of a car or holding the iron bar of a bus after sliding from our seat.
The reason for these experiences is discharge of electric charges through our body due to rubbing of insulating surfaces.
Electrostatics deals with the study of forces, fields and potentials arising from static charges.
