1. quantity, electric Electricity may be measured as if it were a compressible gas, by determining the potential it produces when stored in a defined recipient. In this way the conception of a species of quantity is reached. It is also measured as the quantity of current passed by a conductor.
Thus a body whose surface is more or less highly charged with electricity, is said to hold a greater or less quantity of electricity.
It may be defined in electrostatic or electro-magnetic terms. (See Quantity, Electrostatic--Quantity, Electro-magnetic.)
