WebEach anode is electrorefined until about 80%–85% of the mass has dissolved. Two or three cathode plating cycles are produced from a single anode. Each copper cathode typically weighs 50–160 kg. This multicathode plating cycle ensures that cathodes do not grow too close to the slime-covered anodes and become contaminated. Web(b) When high voltage electricity is passed through a gas taken in a discharge tube, stream of minute particles are given out by the cathode. This happens because the gas taken in the discharge tube consists of atoms and contains electrons. These electrons are excited when electricity passed. These free fast moving electrons are cathode rays.
