The resistance of a galvanometer is 50 ohms and the current required to give full scale deflection is $100\text{\hspace{0.17em}}\mu A$. In order to convert it into an ammeter, reading upto 10A, it is necessary to put a resistance of

(1) $5×{10}^{-3}\text{\hspace{0.17em}}\Omega$ in parallel

(2) $5×{10}^{-4}\text{\hspace{0.17em}}\Omega$ in parallel

(3) ${10}^{5}\text{\hspace{0.17em}}\Omega$ in series

(4) 99,950 Ω in series
