Question
Chapter 38, Problem 1PLA
To determine
The components that make up the electron gun in a cathode-ray tube.
Expert Solution & Answer
Answer to Problem 1PLA
The components that make up the electron gun in a cathode-ray tube are heated filament and the three series of electrodes.
Explanation of Solution
Cathode-ray tube (CRT) is the fundamental working part of an oscilloscope and electron gun is the part of CRT.
It consists of heated filament to emit electron beam and series of electrodes to accelerate, focus, and control the intensity of the electron emitted from the filament.
Together the heated filament and the three series of electrodes are called the electron gun.
Conclusion:
Therefore, the components that make up the electron gun in a cathode-ray tube are heated filament and the three series of electrodes.
