A galvanometer with resistance 3663 ohms has shunt S connected across, such that 1/34 of the total current passes via the galvanometer. Find value of the shunt.

As per the given question, the following can be calculated:

\(\frac{I_g}{I} = \frac{S}{S+G}\)

⇒ \(\frac{1}{34} = \frac{S}{S+G}\)

⇒ \(S\) = \(\frac{G}{33} = \frac{3663}{33} = 111 \ \omega\)
