The resistance of a galvanometer is $50 o hm$ and the maximum current which can be passed through it is $0.002 A .$ What resistance must be connected to it in order to convert it into an ammeter of range $0 - 0.5 A ?$

Options:

Answer:

Solution:

$R_{G} i_{g} = R_{s} i_{s}$

$50 \times 0.002 = R_{s} (0.498)$

$R_{s} = 0.2 O hm$
