Consider the following statements about static electricity:
(I) It is the electricity built up on the surface of a substance.
(II) It is generated by power plants and batteries.
(III) Static electricity is uncontrolled.
Static electricity is the buildup of an electric charge on the surface of objects, which typically occurs through contact or friction between materials. Unlike current electricity, it is not generated by power plants or batteries and is often uncontrolled, leading to sudden discharges like sparks.
