A galvanometer having a coil resistance
100 $\Omega $ gives a full scale deflection when a
current of 1 mA is passed through it. What is
the value of the resistance which can convert
this galvanometer into a voltmeter giving full
scale deflection for a potential difference of
10 V?
8.9 k$\Omega $
10 k$\Omega $
9.9 k$\Omega $
7.9 k$\Omega $
