The ampere is the unit which measures the amount of current.
In order to express quantity of energy, it is necessary to state the length of time the energy is to act and originally the watt represented the energy of a volt-ampere for one second.
The ampere meter or ammeter, as it is termed, is the proper indicator of the strength of the cell.
The volt, ampereand ohm are terms that are used to express the conditions of the electric circuit; the watt and the kilowatt are units that are employed in measuring its quantity in commercial usage.
A filament suitable for an ampere of current is shorter and heavier than that of the 110-volt lamp and therefore furnishes a good form of construction.
