Uses of Static Electricity
Even though static electricity can be unsafe, it has some uses as discussed below: Electrostatic induction can also be applied to spread paint evenly on a surface. Tiny droplets of paint, when given the same charge, repel one another. When sprayed on a surface, such as the body of a car, the paint forms a…
