The electric starter in an automobile equipped with a 12 V battery draws a current of 100.00 A when in operation. Suppose it takes the motor 4.00 s to start the engine. What amount of electric energy has been withdrawn from the battery?
Answer:
(in J) 4.80×103 J
The automobile is equipped with a generator that delivers 5.90 A to the battery when the engine is running. How long must the engine run in order for the generator to restore the energy in the battery to its original level?
Need help with the second question.. not sure how to relate the two.
