Lexicon Volt

Unit for the electrical Voltage. Named after the Italian physicist Alessandro Volta. The unit symbol is the capitalized V.

The electrical voltage is a potential difference between two points. Voltages are therefore always measured between two points on an electrical circuit. If only one point is specified, the other must be inferred from the context. Often this is the mass.

Example: The voltage of a commercial Mignon battery cell is 1.5V. This means the voltage between the negative pole (the bottom) and the positive pole (the nipple on top) of the battery cell.
