Charging by Induction

Van De Graff Generator

It is the production of electric charge on the surface of the conductor under the influence of an electric field.

Consists of

Positive and Negative Charge

Unlike charges attract

Like charges repel

Applied in

Photocopiers

Laser printers

Spraypainting

the car's body is earthed when it is being spray-painted, causing the paint to be attracted to the metal body. The droplets contain the same charge causing them to be evenly spread out

Electrostatic Precipitator

Removes dust particles by earthing the plates within the chimney, while keeping negatively-charged rods in between the metal plates. The air is ionised causing the dust particles to be attracted to the plates.

Hazards

Sparks and fires

Electrostatic Hazards

Examples of materials charged positive or negative

Positive

Glass (rubbed with silk)

Perspex (rubbed with wool)

Negative

Amber (rubbed with fur)

Rubber (rubbed with fur)

Polythene (rubbed with wool)

Electric Fields

the region in which an electric charge experiences a force

Field Lines, It is the path a a positive charge would take if it was free to move.

Electric field between parallel plates

The electric field between the parallel plates is central region., Electric fields are closer to each other in a stronger electric field
