Question

The graph which represents the relation between the total resistance `R` of a multi range moving coil voltmeter and its full scale deflection

A. `(i)`
B. `(ii)`
C. `(iii)`
D. `(iv)`

Answer 1

Correct Answer - D
(d) For conversion of a galvanometer into a voltmeter
`(V)/(R + G) = i_(g) implies (V)/(R_(V)) = i_(g)`
Where `R_(V) = R + G = ` Total resistance
`implies R_(V) = (V)/(i_(g)) implies R_(V) prop V`
