A 5.0 A current is setup in an external circuit by a 6.0 ~V storage battery for 6.0 ~min . The chemical energy of the battery is reduced by

Options

  1. A1.08 10⁴ ~J
  2. B1.08 10⁴ ~V
  3. C1.8 10⁴ ~J
  4. D1.8 10⁴ ~V

Correct answer

A. 1.08 10⁴ ~J

Step-by-step solution

Given, I=5 ~A , V=6 ~V , t=6 ~min =6 60=360 ~s Heat produced in a circuit =Chemical energy reduced in the battery aligned H &=V I t &=6 5 360 &=10800=1.08 10⁴ ~J aligned
