Volt

The practical unit of electro-motive force or potential difference. It may be referred to various data. An electro-motive force of one volt will cause a current of one ampere to flow through a resistance of one ohm. A condenser of one farad capacity charged with one coulomb will have a rise of potential of one volt. The cutting of 100,000,000 lines of force per second by a conductor induces one volt E. M. F. A Daniell's battery gives an E. M. F. of 1.07 volts; about the most familiar approximate standard that can be cited. It is equal to 1/300 absolute electrostatic unit. It is equal to 1E8 absolute electro-magnetic units. [Transcriber's note: The SI definition of a volt: The potential difference acro a conductor when a current of one ampere di ipates one watt of power.]
