A galvanometer having a coil resistance of $100\,\Omega $ gives a full scale deflection, when a currect of $1$ $mA$ is passed through it. The value of the resistance, which can convert this galvanometer into ammeter giving a full scale deflection for a current of $10$ $A,$ is :
$0.1\,\Omega $
$3\,\Omega $
$0.01\,\Omega $
$2\,\Omega $
