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.
With a high voltage applied to the discharge electrodes a strong electrical field is created between the electrodes and the flue gas is ionised, plus-ions migrate to the negative electrode and...
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,...
There is a lot of variation in the applied DC voltages that operate an electrostatic precipitator (ESP). Some work on a few thousand volts (a few kV), while big industrial units might run on upwards...
