Question:medium

A galvanometer is used for making an ammeter of range 500 mA when a shunt of 2 $\Omega$ is used. The same galvanometer is used for making a voltmeter of range 10V when a resistance of 470 $\Omega$ is used in series. Then find the resistance of the galvanometer.

Show Hint

For making an ammeter or voltmeter from a galvanometer, the resistance is adjusted by adding a shunt or a series resistance, respectively. Use the range formulas to calculate the required resistance for the galvanometer.
