Question 60 of 90 in this shift, Physics question 30 of 30, Section B.

In the experiment to determine the galvanometer resistance by half-deflection method, the plot of

\frac{1}{\theta}

vs the resistance (R) of the resistance box is shown in the figure. The figure of merit of the galvanometer is ________

\times10^{-1}

A/division. [The source has emf 2V]

The figure, in words

Straight-line graph of

1/\theta

(div

^{-1}

, vertical axis, marks 1/2, 1, 1 1/2, 2) versus R (Ω, horizontal axis, marks 2, 4, 6). The line has intercept 1/2 on the vertical axis and passes through (R=2, 1), (R=4, 1 1/2) and (R=6, 2), shown with dotted guide lines.
