Is paint a conductor of electricity? Since we charge the paint and let it move to the metal body of a grounded car so an opposite charge on the car. So when the paint reaches the car will the paint get discharged or will the charges on the car remain the same? Like the paint and the car body both have opposite charges and are in contact but the electrons cannot flow to each other. So how does this work? Also, for an electrostatic precipitator there are 2 methods of it. One is the ionization one and the other is when the flue-ash passes through negatively charged wires, but why do they gain a negative charge too? I think its supposed to be charged by friction so how does it gain the same charge? I'm talking about this: http://www.explainthatstuff.com/electrostaticsmokeprecipitators.html As for the ionization one, when the ions flow to their respective plates do the electrons get discharged? Like do they allow electrons to flow out of them and into them? Since they are split into their ions form. Thanks for the help!
