When a current of $\displaystyle 5$ mA is passed through a galvanometer having a coil of resistance $\displaystyle 15 \Omega$, it shows full scale deflection. The value of the resistance to be put in series with the galvanometer to convert it into a voltmeter of range $\displaystyle 0$-$\displaystyle 10$ V is :
Official answer
(1)
$\displaystyle 1.985 \times 10^3 \Omega$
