THE VOLT
The standard unit of electrical potential or potential difference, also called electromotive force (emf), is the volt, symbolized V. One volt is equivalent to one joule per coulomb (1 J/C). The volt is, in real-world terms, a moderately small unit of electrical potential. A standard dry cell of the sort you find in a flashlight (often erroneously called a battery), produces about 1.5 V. Most automotive batteries in the United States produce between 12 and 13.5 V.
