These experiments involve the interaction of electricity with gases at low pressures, observing cathode rays and their properties. A typical discharge tube is a sealed glass tube with electrodes at the ends, a cathode (negative electrode) and an anode (positive electrode). When a high voltage is applied, the gas inside the tube becomes conductive, resulting in electrons emitted from the cathode colliding with gas atoms, resulting in ionization and light emission.\n
