DC VoltmeterMODEL: DCV_48
Analog voltmeters are generally galvanometers connected in series with a high-resistance resistor. They have a coiled spring that moves a needle in response to a magnetic field. The needle is next to a graduated scale, allowing the user to take a reading of the current. Such meters are generally less precise than those using improved technology and digital readouts.
