(c) Voltmeter is an instrument which measure the potential difference between two points. A high resistance is connected in series with coil of the galvanometer to convert it into voltmeter. This resistance is either 2000 Resistance connected in series is given by
Eq. (i) is the value of the resistance required to convert the galvanometer to voltmeter of range 0 to V. From the relation
Hence, |
or more than that.
