i don't have the exact numbers handy, but can anyone help me with this situation - if i have a 5v power supply running an item that is meant to run on 12v, at say 12amps, what amperage would it be at 5v? is it as simple as 5amps? im guessing not but its too long since i did this at school?

Sputnik II said:That's a very long winded way to say that the voltage would be the same as the current for a load of 1 Ohm.But, your spot on.
If the OP could tell us what this electrical item was it would help us to give a more accurate answer based on his question wouldn't it.
sorry, yes it's a lamp. trying to get my head round it still lol, but these posts have really helped thx. i can work out how to wire the circuit, but i need amperage etc for fuses etc.
