rgcaraudio 		Simply use Ohm's Law, i.e., V = IR where V = voltage = 12 v I = current = 25 amp R = resistance and substituting values, 12 = 25(R) R = 0.48 ohm Hope this helps.

rgcaraudio 		here's my guess... from what i remember from college physics, V voltage is equal to the product of I current and R resistance, V=IR. so with this formula, you might be able to have an answer of 0.46 ohms...
