Current Electricity

Question: The resistance of a galvanometer is 50 ohms and the current required to give full scale deflection is $100\,\mu A$. In order to convert it into an ammeter, reading upto 10A, it is necessary to put a resistance of

1) $5 \times {10^{ - 3}}\,\Omega $ in parallel

2) $5 \times {10^{ - 4}}\,\Omega $ in parallel

3) ${10^5}\,\Omega $ in series

4) $99,950\,\Omega $in series
