How a photocopier works (1 Viewer)

[superbird]

Could somebody please clarify whether we need to know this. I think we also need to know about lightning rods aswell correct?

 

[jumb]

Nah they arent in the sylabus.

 

[garry]

outline the role of:
– electrodes in the electron gun
– the deflection plates or coils
– the fluorescent screen
in the cathode ray tube of
conventional TV displays and
oscilloscopes

Lightning Rods yes
 gather and analyse information to identify how transmission lines are:
– insulated from supporting structures
– protected from lightning strikes

Photocpiers no, they were taken out in the cull

 

[garry]

the insulator was made of porcelain but i just know they use protecting wire to protect lightning strikes. so is the protecting wire a lightening rod?

 

[helper]

Some transmission poles have rods, so in that sense only.

Nah, there was another dot point that mentioned how corona wires are used in Lightning Rods and Photocopiers. I think it's been taken out.
