permanent-magnet moving-coil voltmeter
1Voltmeter — Demonstration voltmeter from a physics class A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage… …
2Galvanometer — D Arsonval/Weston galvanometer movement with the moving coil shown in red. A galvanometer is a type of ammeter: an instrument for detecting and measuring electric current. It is an analog electromechanical transducer that produces a rotary… …
3Ammeter — Amperemeter redirects here. For the unit of measurement, see Ampere meter. Demonstration model of a moving iron ammeter. As the current through the coil increases, the plunger is drawn further into the coil and the pointer deflects to the right …
