Question

We have a galvanometer of resistance $25 Ω$ It is shunted by a $2.5 Ω$ wire. The part of total current that flows through the galvanometer is given as

Moderate

A

$\frac{i_{g}}{i} = \frac{1}{11}$
B

$\frac{i_{g}}{i} = \frac{1}{10}$
C

$\frac{i_{g}}{i} = \frac{3}{11}$
D

$\frac{i_{g}}{i} = \frac{4}{11}$

Solution

$\frac{i}{i_{g}} = \frac{G + S}{S} \Rightarrow \frac{i_{g}}{i} = \frac{S}{G + S} = \frac{2 .5}{27 .5} = \frac{1}{11}$
