WebNov 28, 2024 · The positive electrode is called anode and the negative electrode is called cathode. When a high voltage is applied between the cathode and the anode, the electrons are accelerated at high speed from the cathode to the anode. This stream of electrons which is moving at high speed is called cathode rays. People also ask. WebThe electrons are being provided by the power supply in whatever device the CRT is in. The cathode has an electrical connection to the outside of the tube to give the cathode a charge. Once the electrons strike the tube, they do tend to gather there for a while until they leak away. WebAs the cathode rays travel toward the right, they are deflected toward the positive electrode (+), demonstrating that they are negatively charged. Image used with Permission (CC BY-SA-NC).
