Question
When a $12 \Omega$ resistor is connected with a moving coil galvanometer then its deflection reduces from 50 divisions to 10 divisions. The resistance of the galvanometer isa. $24 \Omega$h $36 \Omega$c. $48 \Omega$d. $60 \Omega$
Step 1
In the first case, the current through the galvanometer (Ig) is given by the voltage across it divided by its resistance (Rg). We can write this as: \[Ig = \frac{V}{Rg}\] Show more…

The deflection in moving coil Galvanometer is reduced to half when it is shunted with a $40 \Omega$ coil. The resistance of the Galvanometer is (c) $40 \Omega$ (a) $60 \Omega$ (b) $\overline{10 \Omega}$ (d) $20 \Omega$
The deflection in a Galvanometer falls from 50 division to 20 when $12 \Omega$ shunt is applied. The Galvanometer resistance is (a) $18 \Omega$ (b) $36 \Omega$ (c) $24 \Omega$ (d) $30 \Omega$
A galvanometer of resistance $50 \Omega$ is connected to a battery of $3 \mathrm{~V}$ along with a resistance of $2950 \Omega$ in series. A full scale deflection of 30 divisions is obtained in the galvanometer. In order to reduce this deflection to 20 divisions, the resistance in series should be $\quad$ [Kerala CET 2008] (a) $6050 \Omega$ (b) $4450 \Omega$ (c) $5050 \Omega$ (d) $5550 \Omega$ (e) $5578 \Omega$
