WebAug 7, 2024 · In a cathode ray tube (CRT), the intensity of the electron beam is regulated by the control grid. The control grid is a negatively charged wire mesh that is located between the cathode and the anode of the CRT. The control grid is used to control the flow of electrons from the cathode to the anode. WebA CRT is an electronic tube designed to display electrical data. The basic CRT consists of four major components. Electron Gun Focussing & Accelerating Anodes Horizontal & Vertical Deflection Plates Evacuated Glass Envelope 1.
