Alt. of Ampere - ampere (n.)
The unit of electric current; -- defined by the International Electrical Congress in 1893 and by U. S. Statute as, one tenth of the unit of current of the C. G. S. system of electro-magnetic units, or the practical equivalent of the unvarying current which, when passed through a standard solution of nitrate of silver in water, deposits silver at the rate of 0.001118 grams per second. Called also the international ampere.

ampere
The practical unit of electric current strength. It is the measure of the current produced by an electro-motive force of one volt through a resistance of one ohm. In electric quantity it is the rate of one coulomb per second. It is one-tenth the absolute C. G. S. unit of current strength. Its best analogy is derived from water. Assuming the electric current to be represented by a current of water, the pressure, head, or descent producing such current would be the electro-motive force. The current might be measured in gallons (or other unit) passed per second. In the analogy these gallons would be coulombs. But it might be measured by reference to a standard stream, as for instance, the stream which would pass through a hole an inch square under a given head, say six inches of water. This unit is the miner's inch, and is the exact analogy of the ampere. A current of water may flow at the rate of so many miner's inches, just as a current of electricity may flow at the rate of so many amperes. In neither case it will be noted is there any reference to time. "An ampere per second" is a redundant expression, and means no more than "an ampere"; an "ampere-second," on the other hand, is a coulomb. The number of coulombs passed per second gives the amperes of current.For value of ampere, see Coulomb.straight parallel conductors of infinite length and negligible cross-section, 1 metre apart in vacuum, would produce a force equal to

The ampere or amp (Symbol: A) is the standard unit of electric current. For instance, an electric current of one amp is one coulomb per second. The amp is named after André-Marie Ampère who studied electromagnetism.
The amp is defined using two parallel wires placed one metre apart in a vacuum. The wires are very long and very thin. One amp is defined as the current producing an attractive force of 2×10–7 Newton per metre of length between these wires.
