NEET Physics Current Electricity Questions Solved

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

(1) (i)

(2) (ii)

(3) (iii)

(4) (iv)

(4) For conversion of a galvanometer into a voltmeter

$\frac{V}{R + G} = i_{g}$ ⇒ $\frac{V}{R_{V}} = i_{g}$ ; where R_V = R + G = Total resistance ⇒ $R_{V} = \frac{V}{i_{g}}$ ⇒ $R_{V} \propto V$
