Origin of ammeteram(pere) + -meter
An instrument for measuring electric currents in amperes.
Origin of ammeteram(pere) -meter
- A device that measures the magnitude of an electric current, especially one calibrated in amperes.
- Such an instrument is called a shunted movable coil ammeter, and is represented by a type of instrument shown in fig.
- 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.
