Pragya Gautam 7 years, 3 months ago

The triboelectric effect ( also know as tribo electric charging) is a type of contact electrification on which certain materials become electrically charged after they come into frictional contact with a different material. Rubbing glass with fur, or a plastic comb through the hair, can build ul triboelectricity.
