Can someone upload a simplified igcse CRO diagram?!

[JimmyCarter]

a one that i can use to draw in my physics ig exam if they asked me to, just like in 2011 summer p3 v1

I'm not really good at drawing, but the pieces that you usually need are: Heating Filament, Cathode, Accelerating Anode, Y-Plates, X-Plates, Electron Beam and Fluorescent Screen.

MAN!!! ITS GREAT EXACTLY WHAT I NEEDED!!! I just didnt how to present it. God Bless you!!

whatare the purpose of heather , cathode and anode ??

 

[mrnt3250]

The heater: Generates heat.
Cathode: It is heated by a low voltage current to emit electrons by thermionic emission. Higher current flowing through the filament will produce more thermionic electrons resulting in a brighter spot on the fluorescent screen.
Accelerating anode: This accelerates the cathode rays giving them enough energy so that the screen can fluoresce (a bright spot) when the cathode rays hit it. It is usually connected to the positive terminal of a high d.c. voltage of a few kV.

It hasn't been asked in so many years and now after all these years they DO ask it.
makes you scared doesn't it?
