Battery of 12 V supplies charge of 1000 C to a device work battery

W = 12 kJ

Explanation:

We have,

Voltage of a battery is 12 V

Charge supplied by the battery is 1000 C

It is assumed to find the work is done by the battery in moving the charge. The work done is given in terms of voltage as :

or

W = 12 kJ

So, the work of 12 kJ is done by battery in moving charges.
