Solution 20CQ

Static electricity refers to the build-up of electric charges on the surface of a material as a result of friction. The surface can get rid off this excess charge if the latter gets a conducting pathway to flow out of the surface.

Such a discharge of excess charges results in an electric shock of power of a few hundred watts. But static electricity depends on the number of excess electric charge carriers. Larger is the number of charge carriers, the higher will...
