#### Measurements Lab Manual Capacitor Voltage

A voltmeter is a modified form of galvanometer especially used to measure the potential difference. Instead of using a small resistance in parallel to the galvanometer as in case of an ammeter, we use a large resistance in series. The construction of a voltmeter is shown below.

#### Analog Electrical Devices and Measurements Chula

Example: A PMMC instrument has FSD of 100 µA and a coil resistance of 1700 ?is used in the half-wave rectifier voltmeter. The silicon diode (D1) must have a minimum (peak) forward current

#### pmmc measuring instrument [PDF Document]

PMMC Ammeter Principle PMMC Ammeter: When current carrying conductor placed in a magnetic field , a mechanical force acts on the conductor, if it is attached to a moving system, with the coil movement, the pointer moves over the scale.

#### Unit 2 â€“ Direct Current Meters BRADBURY

If a particular meter read full-scale with 100uA, and dropped 0.01 volts with that much current, one could use it directly as an ammeter for reading currents up to 100uA, or as a voltmeter for voltages up to 0.01 volts, but many real-world applications require reading higher currents or voltages.

#### How Does The Ammeter Work? YouTube

Voltmeter Definition: The instrument which measures the voltage or potential difference in volts is known as the voltmeter. It works on the principle that the torque is generated by the current which induces because of measurand voltage and this torque deflects the pointer of the instrument.
