A galvanometer of resistance 502 giving ...

A galvanometer of resistance 502 giving full scale deflection for a current of 10 milliampere is to be changed into a voltmeter of range 100 V.
A resistance of ……… `Omega` has to be connected in series with the galvanometer

A

9950

B

10025

C

10000

D

9975

Text Solution

Verified by Experts

The correct Answer is:
A

`100= (R+50) xx 10 xx 10^(-3)`
`R+ 50 = 10000 implies R= 9950`
