The starter motor of a car draw a current I=300 ~A from the battery of voltage 12 V . If the car starts only after 2 minutes, what is the energy drawn from the battery?

Options

  1. A3 kJ
  2. B30 kJ
  3. C7.2 kJ
  4. D432 kJ

Correct answer

D. 432 kJ

Step-by-step solution

Energy drawn from the battery aligned E & =V I t & =12 300 2 60 & =432 10^3 ~J & =432 ~kJ aligned
