1.

Explain the concept of static charge.

Answer»

1. Static charges can be created whenever there is a friction between an insulator and other object.

2. For example, when an insulator like rubber or ebonite is rubbed against a cloth, the friction between them causes electrons to be transferred from one to the other.

3. This property of insulators is used in many applications such as photocopier, inkjet printer, painting metal panels, electrostatic precipitation/separators etc.
