It might be an idea to change your signature, do you have your firms permission to use their name on these forums :no:

Polarised

eg, In a Diode current will only flow one way so is therefore polarised, there are some components that are polarised. So a polarised capacitor must go + to + and - to -.

The older I get, the faster I was.

polorized would normally apply to dc voltage's as applied to components, ie a carbone resisitor is not 'polorised' as it is not bothered which way the current flows through it. try reversing the supply to an older style LED or electrolytic capacitor and you get a nasty smell of fused plastic and if lucky a loudish bang to go with it.

wear eye protection and keep mouth tightly closed well before trying it.

i do not recommend or condone this experiment to anyone, and i have never performed it with the great big dc capacitors as found in old tv sets, dangled through a letterbox on a pair of wires using a borrowed motor bike battery, well not since i was 14 and got caught :P
