Static Electricity - the word static means 'at rest' - this kind of electricity exists when objects separated by an insulator has a build up of opposite charges. Because the attraction between these charges is so strong, they can flow even through great insulators. Ex: lightning, friction
Current Electricity - it makes electronic devices possible. There is a constant flow of charges in this type of electricity. In contrast to static electricity, current electricity is changing, dynamic and always on the move. Ex: starting a car, watching TV, using an electric stove.
