what are volts

Volts are the unit of electric potential, electric potential difference, and electromotive force in the International System of Units. One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. In simpler terms, voltage is the difference in electrical potential, or the number of electrons, between any two points in an electrical circuit. Voltage is measured in volts and is represented by the letter “V” in electrical equations. Voltage is also a measurement of the electric potential or "pressure" at which electricity flows through a system. The characteristics of voltage are like that of water flowing through pipes, and this is known as the "water-flow analogy".
