Question

what is a gas dischargetube?write the conditions that are necessary for the production of cathode rays.​

Answer 1

Explanation:

A gas-filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope.

Gas Discharge Tubes (GDTs) are used to protect personnel and sensitive equipment from hazardous transient voltages. Bourns® GDTs are used in primary and secondary applications and can withstand multiple applications of high surge current energy in excess of 25 KA.

The usual conditions maintained in a discharge tube are 10kv to 50 kv DC potential between cathode and anode and a gas pressure of less than 0.014 Pa.
