The 12V battery in your car operates a 25 amp car stereo. What is the resistance of this stereo system?

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

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...
