Question

How much energy is given to each coulomb of charge passing through a 6 V battery?

Answer 1

The overall energy offered to every coulomb of the charge is similar to the overall amount of work that is performing in moving it is given below.

It is a well-known fact that the work done is equal to potential difference × charge.  

The potential difference is 6 V and charge is 1 C.

The work done is equal to 6 Joule.

Answer 2

Given

Q= 1 C

V = 6 V

V = W/Q

W = Q × V

work done = 1 C × 6 V

= 6 J

Energy = Work done

Energy = 6 J
