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 [MP PMT 1997; AIIMS 1999]

• A.                    \[5\times {{10}^{-3}}\,\Omega \] in parallel       
• B.            \[5\times {{10}^{-4}}\,\Omega \] in parallel
• C.                    \[{{10}^{5}}\,\Omega \] in series                            
• D.            \[99,950\,\Omega \]in series
