electrostatics are used in a number of things such as didphone copiers and clearing smoke. it is the branch of physics that deals with electro magnetics. It is also used in painting cars.
In general, a photocopier has a imaging drum made of a material known as a photoconductor. The drum is initially charge with a negative charge. When you put the document and hit the photocopy button,...
The photoconductor drum is charged. The drums is designed so that light causes it to discharge. The areas of charge and discharge are isolated so that patterns can be made. This light and dark areas...
We use DC voltages in an electrostatic precipitator (ESP) because it is necessary to induce a charge on the particulates, and then attract them to a plate by the use of an opposite charge. An AC...
