We know that the potential difference between two points is given by the equation, V = W/Q,
where, W is the work done in moving the charge from one point to another Q is the charge
From the above equation, we can find the energy given to each coulomb as follows: W = V × Q
Substituting the values in the equation, we get W = 6V × 1C = 6 J
Hence, 6 J of energy is given to each coulomb of charge passing through a 6 V of battery.Answered by Shivani Kumari | 2 years ago
