9 Grammatical Pitfalls
A unit of electromotive force in the Internation System of Units that will produce a current of 1 ampere in a circuit that has resistance of 1 ohm.
The SI derived unit used to measure electric potential at a given point, usually a point in an electric circuit. A voltage difference of one volt drives one ampere of current through a conductor that has a resistance of one ohm. One joule of work is required to move an electric charge of one coulomb across a potential difference of one volt. One volt is equivalent to one joule per coulomb. See also Ohm's law.
Note: Ordinary household outlets are usually rated at 115 volts, car batteries at 12 volts, and flashlight batteries at 1.5 volts.
