(N/A) All of us have the experience of seeing a spark or hearing a crackle when we take off our synthetic clothes or sweaters,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 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 the discharge of electric charges through our body due to the rubbing of insulating surfaces (triboelectric effect).
Electrostatics deals with the study of forces,fields,and potentials arising from static charges.
