nAmpèremeter(Physics) An instrument for measuring the strength of an electrical current in ampères.
Century Dictionary and Cyclopedia
namperemeterIn electricity, an instrument for measuring the strength of an electric current in amperes. Several forms have been devised, some of which are essentially galvanometers specially constructed for this purpose. Another form (see the cut) consists of a hollow coil of wire traversed by the current to be measured, which according to its strength draws within itself a core supported by a spring and having an index attached to it; the scale is so graduated that the strength of the current is given directly in amperes. Also called ammeter, amperometer.
