The conversion of a moving coil galvanometer into a voltmeter is done by
A
(a) Introducing a resistance of large value in series
A
(b) Introducing a resistance of small value in parallel
A
(c) Introducing a resistance of large value in parallel
A
(d) Introducing a resistance of small value in series
Explanation
Solution
(a) The equivalent circuit of conversion of galvanometer in voltmeter is given by
Because of this connection the circuit draw a very small current from the source that is helpful for measurement of voltage across the circuit
