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