A milli voltmeter of 25 milli volt range is to be converted into an ammeter of 25 ampere range. The value (in ohm) of necessary shunt will be

Options:

Answer:

Solution:

Galvanometer is converted into ammeter, by connected a shunt, in parallel with it.
$\frac{GS}{G + S} = \frac{V _{G}}{I} = \frac{25 \times 1 0 ^{- 3}}{25} \frac{GS}{G + S} = 0.001Ω$ Here $S < G$ so $S = 0.001Ω$
