In a CRO which of the following is not a part of electron guncathodegridacceleration anodex-y platesanode

To determine which option is not part of the electron gun in a Cathode Ray Oscilloscope (CRO), let's briefly examine each component mentioned:

1. Cathode: This is a fundamental part of the electron gun where the electron beam is emitted.
2. Grid: The grid is used to control the flow of electrons from the cathode to the anode.
3. Acceleration Anode: This component accelerates the electrons towards the screen, making it crucial for the functioning of the electron gun.
4. X-Y Plates: These are typically used for deflection of the electron beam and are not part of the electron gun itself.
5. Anode: This component collects the electrons after they have passed through the system, playing a significant role in the electron gun.

Conclusion

The X-Y plates are not part of the electron gun; they are part of the deflection mechanism in a CRO. The rest of the components listed are integral to the electron gun assembly.
