Question
Write down the phenomena seen or observed during the generation of static electricity.
✓

Answer

► 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.
► This is almost inevitable with ladies garments like a polyester saree.
►Another common example of electric discharge 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, which were accumulated due to rubbing of insulating surfaces.
► Static means anything that does not move or change with time.
