If only one hundredth part of total current flowing in the circuit is to be passed through a galvanometer of resistance $G$ , then the value of shunt resistance required will be -

Options:

Answer:

Solution:

Using Kirchoff's Loop law

$i_{g} G = (i - i_{g}) S$

$\frac{i}{100} G = (i - \frac{i}{100}) S$

$\frac{G}{100} = \frac{99 S}{100}$

$S = \frac{G}{99}$
