This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See AnswerSee AnswerSee Answerdone loading 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.
