I understand that there are many different kinds of electrostatic precipiators but I'm referring to the type where a negatively charged wires are placed in between two grounded plate. This essentially makes it a positive plate. So when the smoke rises up they are ionized and thus the ions are attracted to their respective plates/rods. However, the part I'm confused about is whether they are able to accept electrons or give them up when they reach the plate/wires. Meaning do the electrons from the negatively charged wires get given up to the ions and they form molecules again while for the grounded plates do electrons flow into the plate and get grounded and form molecules too? Thanks for the help!
