conductors and insulators

[12joe340]

What is the best conductor and what is the best insulator ? i also need to know what are the reasons for this.

[Einion Yrth]

Do your own homework.

cant be bothered :P id rather play on magic pen

Do you still get "conductors"? I thought they were now "guards" on trains and "drivers" on buses

What are you trying to achieve?

[esselte]

Squirrels appear to be very good conductors,at least around our area....

Copper is the best conductor. Not the best, but the most useful and practical. It has a low resistance, is relatively cheap, and is quite flexible. The colder the better.

The best insulator is a vacuum - no means for the electricity to bridge the gap.

Euphemism?

[motco]

It all depends on what you mean by the terms. What frequency, what temperature, what voltage, what humidity...?

Can't answer you anyway, but you ought to realise what you're up against.

If electricity is the movement of electrons and electrons are used to form TV pictures, if you are correct then how do they traverse the vacuum in the CRT to hit the screen? Or have I got it totally wrong...?

[12joe340]

im guessing the best insulator is some form of rubber polymer or maybe helium ?

[Roop]

Conductor of what...? Copper is a pretty cack conductor of light last time I checked.

So - Heat, light, electricity, sound etc...

I'm sorry, I suppose it was a bit of a rhetorical question,I do know how a crt works.....I was just asking how,if a vacuum is the best insulator,can the electrons in a crt display traverse it....

The big wall around the outside stops the electricity getting in?
