ampere

Definition: Unit of current or rate of flow of electricity. * Unit A; informally: amp. * In a circuit, current increases as resistance decreases, and vice versa, for a given voltage.
Abstract current
The strict definition of ampere is opaque to all but physicists: it is defined in terms of the electrical field between two infinitely thin, infinitely long conductors in a vacuum (if you must know: an ampere is that current which produces a force of 2x10-7N between those wires).
