The potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the other.
The potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the other.
Unit of current is ampere. If one coulomb of charge flows through any section of a conductor in one second then the current through it is said to be one ampere. I = Qt or 1 A = I C s-1

How much energy is given to each coulomb of charge passing through a 6 V battery?
Energy given by battery = charge x potential difference or W = QV = 1C X 6V = 6J.
Energy given by battery = charge x potential difference
See lessor W = QV = 1C X 6V = 6J.
What is meant by saying that the potential difference between two points is 1 V?
The potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the other.
The potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the other.
