High resistance in series with galvanometer.

(C) voltmeter is always connected in parallel to a circuit to measure the potential difference across it. Since a galvanometer is a very sensitive instrument,it cannot directly measure high potential differences. To convert a galvanometer into a voltmeter,a very high resistance,often called a multiplier or series resistance,is connected in series with the galvanometer. This increases the total resistance of the device,allowing it to measure higher voltages without drawing excessive current.
