Question

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

Answer 1

The energy given to each coulomb of charge is equal to the amount of work which is done in moving it.

Now we know that

Potential difference =

∴ Work done = Potential difference × charge

Where, Charge = 1 C and Potential difference = 6 V

∴ Work done = 6×1

= 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
