A milli-voltmeter of 25 milli-volt range...

A milli-voltmeter of 25 milli-volt range is to be converted into an ammeter of 25 ampere range. The value (in ohm) of necessary shunt will be:

A

0.001

B

0.01

C

1

D

0.05

Text Solution

Verified by Experts

The correct Answer is:
A
The value of necessary shunt(s) will be
`S=(V_(g))/((l-l_(g)))," Neglecting "l_(g)`
`:." "S=(V_(g))/(l)`
`S=(25xx10^(-3)V)/(25A)=0.001Omega`
