PhysicsEasysingle choice

In a galvanometer, $5 %$ of the total current in the circuit passes through it. If the resistance of the galvanometer is $G$ , the shunt resistance $S$ connected to the galvanometer is

Options:

Answer:

Solution:

The shunt of an ammeter,

$S = \frac{I_{g} \times G}{I - I_{g}}$

$= \frac{5 \times G}{100 - 5} = \frac{G}{19}$
