Question 164: Current Electricity

Question

The deflection in moving coil galvanometer falls from 25 divisions to 5 division when a shunt of $$24 \Omega$$ is applied. The resistance of galvanometer coil will be :

Accepted Answer

Let x = current/division
After applying shunt
Now $$5 \mathrm{x} 	imes \mathrm{G}=20 \mathrm{x} 	imes 24$$
$$\begin{aligned}
& \mathrm{G}=4 	imes 24 \
& \mathrm{G}=96 \Omega
\end{aligned}$$

Answer

$$48 \Omega$$

Answer

$$100 \Omega$$

Answer

$$96 \Omega$$

Answer

$$12 \Omega$$
