Who discovered discharge tube?

A Crookes tube is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. read more

Discharge tube is a glass tube fitted with two electrodes placed opposite to each other. The tube is sealed and contains a vacuum pump. The function of vacuum pump is to reduced or change the pressure inside the tube. read more

Gas discharge tubes Glow discharge in a low-pressure tube caused by electric current. In 1838, Michael Faraday passed a current through a rarefied air filled glass tube and noticed a strange light arc with its beginning at the cathode (negative electrode) and its end are at the anode (positive electrode). read more

discovery of the electron cathode rays Most of the information about electrons is obtained from the study of cathode rays, which were discovered during the experiments with gas discharge tubes. A discharge tube is long glass tube, such as shown in Fig. 5.2. read more
