>What you need to know is Watts, which BTW is how we Canadians measure power > consumption. So we pull out Ohms Law which states R = V/I (V= Volts, I= > Current, R= Resistance). Resistance is the same as Watts in this case. What on earth are you talking about :-) (:- W = I * V or 38 Ah well, at elast the Greate British education system can't be THAT bad, though it pretty grim.
