Question

In a CRT the magnitude of the beam current can be adjusted by a front panel control marked:

• A. Intensity
• B. Time/div
• C. Focus
• D. Volts/div

Hint:

Intensity control adjusts the brightness in CRT displays by varying the beam current, while other controls adjust the time scale, focus, and voltage.

Answer 1

The Correct Option is A

In a cathode ray tube (CRT), the intensity control adjusts the magnitude of the beam current. This affects the brightness of the image on the screen. Other controls like Time/div, Focus, and Volts/div control other aspects of the display but not the beam current. Thus, the correct answer is Intensity.
