The electron gun in cathode ray oscilloscope consists of:
Correct answer: D. All of the above
- A. Grid
- B. Three anodes
- C. Indirectly heated cathode
- D. All of the above
Explanation
The electron gun in a cathode ray oscilloscope includes an indirectly heated cathode. The cathode is responsible for emitting electrons when heated by a filament. These emitted electrons form the electron beam, which is then accelerated and focused by other components of the electron gun.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
