An instrument for measuring electric currents in amperes.
Origin of ammeteram(pere) -meter
An instrument that measures the strength of an electric current, indicating it in amperes. Ammeters typically include a galvanometer; digital ammeters typically include A/D converters as well.
- A device that measures the magnitude of an electric current, especially one calibrated in amperes.
- The capacity of the condenser is then altered until the maximum current, as indicated by a hot wire ammeter, is produced in the circuit.
- AMPEREMETER, or Ammeter, an instrument for the measurement of electric currents in terms of the unit called the ampere.
- Another form of hot-wire ammeter is a modification of the electric thermometer originally invented by Sir W.
- A steady continuous current is then passed through the ammeter and low resistance, placed in series with one another and adjusted so as to give any required scale reading on the ammeter.
- In its simplest form an electromagnetic ammeter consists of a circular coil of wire in which is pivoted eccentrically an index needle carrying at its lower end a small mass of iron.
