Question

A galvanometer has a resistance of 3663 $\omega$. A shunt S is connected across it such that 1/34 of the total current passes through the galvanometer. The value of the shunt is

• A. 3663 $\omega$
• B. 111 $\omega$
• C. 107.7 $\omega$
• D. 3555.3 $\omega$

Answer 1

The correct option is B 111 $\omega$

$\frac{I_g}{I}=\frac{S}{S+G}$

or

$\frac{1}{34}=\frac{S}{S+G}$

$\therefore S=\left(G/33\right)=\left(3663/33\right)=111\omega$
