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.
- 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.
- 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.
- There is therefore a certain ratio in which any current passing through the ammeter is divided between the shunt and the working wire.
- If these conditions are not fulfilled sufficiently, the ammeter will not give the same indications for the same current if that current has been reached (a) by increasing from a smaller current, or (b) by decreasing from a larger current.
