Question
How much energy is given to each coulomb of charge passing through a 6 V battery?
Solution
The energy given to each coulomb of charge equals the amount of work done to move it.
Now we know that,
Potential difference = `("Work Done")/("Charge")`
∴ Work done = Potential difference × charge
Where, Charge = 1 C and Potential difference = 6 V
∴ Work done = 6 × 1
= 6 Joule.
