The resistance of a galvanometer is 50 ohm and the maximum current which can be passed through it is 0.002 A. what resistance must be connected to it in order to convert it into an ammeter of range 0-0.5 A ?

A

0.02 ohm

B

0.002 ohm

C

0.2 ohm

D

0.5 ohm

Text Solution

Verified by Experts

The correct Answer is:
C
`(I - I_(g)) xx S = I_(g) G, S = ((0.002 xx 50)/(0.5 - 0.002)) = 0.2 Omega`
