How can you use a galvanometer as a voltmeter
WebDC voltmeter is a measuring instrument, which is used to measure the DC voltage across any two points of electric circuit. If we place a resistor in series with the Permanent Magnet Moving Coil (PMMC) galvanometer, then the entire combination together acts as DC voltmeter..

Web8 de jan. de 2015 · These days "in modern times" with circuit advances being made in semiconductor devices that have ability for input impedance levels up to the 100s if not 1000s of megohms it is possible to sense a change in the balance of a bridge without having to use the classic galvanometer mechanism. Web23 de fev. de 2024 · 1. Find a voltage scale on the needle's dial. Choose one that matches the setting you chose on your voltmeter's knob. If there is no exact match, read from a scale that's an easy multiple of the setting. For example, if your voltmeter is set to DC 10V, look for a DC scale with a max reading of 10.
