A car battery has a voltage of epsilon = 12 V To turn the starter on a car the battery must supply I = 444 A. It takes t = 4.8 s for the engine to start. Input an expression for the total charge passed through the starter, Q. How much energy did the starter consume, E, in J?

Solution

A)

total charge passed on to starter = I * t = 444A* 4.8 s= 2131.2 C

B)

ENERGY CONSUMED IN JOLUE = V* I * T = 12 * 444 * 4.8 S = 25574 J
