What is the difference between potential and potential difference?

Potential Difference. Potential difference , or voltage, is the difference in electric potential energy between two points. It is denoted by ∆V and has units of volts, or joules per Coulomb. Potential is the specific potential energy.

Besides, what is the symbol of potential difference?

The volt (symbol: V) is the derived unit for electric potential, electric potential difference, and electromotive force. The volt is named in honour of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, possibly the first chemical battery.

What is the difference between potential energy and potential?

Electric potential energy is the potential energy stored when charges are out of equilibrium (like gravitational potential energy). Electric potential is the same, but per charge, U e q . An electric potential difference between two points is called voltage, V = U e 2 q − U e 1 q .
