When a current of \(5~\text{mA}\) is passed through a galvanometer having a coil of resistance \(15~\Omega\), 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 \(0\text{-}10~\text{V}\) is:
1. \( 1.985 \times 10^3 ~\Omega \)
2. \( 2.045 \times 10^3 ~\Omega \)
3. \( 2.535 \times 10^3 ~\Omega \)
4. \( 4.005 \times 10^3 ~\Omega\)

The resistance of a galvanometer is \(50~\Omega\) and the maximum current which can be passed through it is \(0.002~\text{A}\). What resistance must be connected to it in order to convert it into an ammeter of range \((0\text-0.5~\text{A})?\)
1. \(0.2~\Omega\)
2. \(0.002~\Omega\)
3. \(0.02~\Omega\)
4. \(0.5~\Omega\)
