Problem

In a circuit for finding the resistance of a galvanometer by half deflection method, a 6 V battery and a high resistance of

11\text{k}\Omega

are used. The figure of merit of the galvanometer is

60\mu\text{A/division}

. In the absence of shunt resistance, the galvanometer produces a deflection of

\theta = 9

divisions when current flows in the circuit. What value of shunt resistance will cause the deflection to become

\theta/2

? (1)

55\Omega

(2)

110\Omega

(3)

220\Omega

(4)

550\Omega
