A galvanometer gives full scale deflection when current passed throguht it is 1 m A. its resistance is ` 100 Omega`. Without connecting additional resistance in series with it , can be used as a voltmeter of range

A

1,000 V

B

0,100 V

C

0,010 V

D

0,001 V

Text Solution

Verified by Experts

The correct Answer is:
B
As galvanometer gives full scale deflection for a current of `1mA` and its own resistance is `100Omega`, hence without connecting additional resistance it can be used to measure the maximum voltage which is given by ,
`I_g G=0^-3xx100=0.1V`.
i.e., it can be used as a voltmeter of range `0.1V`.
