Question 242: Current Electricity

Question

A current of $200 \mu \mathrm{A}$ deflects the coil of a moving coil galvanometer through $60^{\circ}$. The current to cause deflection through $\frac{\pi}{10}$ radian is :

Accepted Answer

$\mathrm{i} \propto 	heta$ (angle of deflection)
$\begin{aligned}
& 	herefore \frac{\mathrm{i}_2}{\mathrm{i}_1}=\frac{	heta_2}{	heta_1} \Rightarrow \frac{\mathrm{i}_2}{200 \mu \mathrm{A}}=\frac{\pi / 10}{\pi / 3}=\frac{3}{10} \
& \Rightarrow \mathrm{i}_2=60 \mu \mathrm{A}
\end{aligned}$
