The Story of Electricity

by John Munro

III. ELECTROSTATIC UNITS.—

UNIT QUANTITY of electricity is that which repels an equal and similar quantity at unit distance with unit force in air.

UNIT CURRENT is that which conveys unit quantity of electricity along a conductor in a second.

UNIT ELECTROMOTIVE FORCE, or unit DIFFERENCE OF POTENTIAL exists between two points when the unit quantity of electricity in passing from one to the other will do the unit amount of work.

UNIT RESISTANCE is that of a conductor through which unit electromotive force between its ends can send a unit current.

UNIT CAPACITY is that of a condenser which contains unit quantity when charged to unit difference of potential.
