What is meant by saying that the potential difference between two points is 1 V?
Answer
We know that
Potential Difference = Work done/ Charge
∴ 1 Volt = 1 Joule / 1 Coulomb
So, we can say that
Potential difference between two points is said to be 1 volt when 1 Joule of work is done to move a charge of 1 Coulomb from one point to another.
