MCQ
The graph which represents the relation between the total resistance $R$ of a multi range moving coil voltmeter and its full scale deflection $V$ is
- A$(i)$
- B$(ii)$
- C$(iii)$
- D$(iv)$
$\frac{V}{{R + G}} = {i_g}$ $ \Rightarrow $ $\frac{V}{{{R_V}}} = {i_g}$;
where $R_V = R + G = $
Total resistance $ \Rightarrow $ ${R_V} = \frac{V}{{{i_g}}}$ $ \Rightarrow $ ${R_V} \propto V$
