Question
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) $20 \Omega$
Step 1
Shunting is the process of adding a resistor in parallel to the galvanometer to increase its range. The shunt resistor and the galvanometer form a parallel circuit, and the total resistance of this circuit is less than the resistance of the galvanometer. Show more…

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 is a. $24 \Omega$ h $36 \Omega$ c. $48 \Omega$ d. $60 \Omega$
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 moving coil galvanometer gives full scale deflection, when a current of $0.005 \mathrm{~A}$ is passed through its coil. It is converted into a voltmeter reading upto $5 \mathrm{~V}$ by using an external resistance of $975 \Omega$. What is the resistance of the galvanometer coil? (a) $30 \Omega$ (b) $25 \Omega$ (c) $50 \Omega$ (d) $40 \Omega$
