How do photocopiers use static electricity? For a photocopier to work, a field of positive charges must be generated on the surface of both the drum and the copy paper. These tasks are accomplished by the corona wires. These wires are subjected to a high voltage, which they subsequently transfer to the drum and paper in the form of static electricity.
How does a photocopier use static electricity GCSE? The way this selectivity is accomplished in a copier is with light — this is why it’s called a photocopier! Somehow the toner has to get onto the drum and then onto a sheet of paper. The drum selectively attracts toner. Then the sheet of paper gets charged with static electricity and it pulls the toner off the drum.
Can electrical wiring be water damaged? When wire and cable products are exposed to water or excessive moisture, the components may be damaged due to mildew or corrosion. This damage can result in insulation or termination failures. … Wire and cable that is listed for dry locations only, such as NM-B, should be replaced if it has been exposed to floodwater.
