The range of a voltmeter of resistance `500 Omega` is 10V. The resistance to be connected to convert it into an ammeter of range 10 A is-

A

`1 Omega` is parallel

B

`1 Omega` in series

C

`0.1 Omega` in parallel

D

`0.1 Omega` in series.

Text Solution

Verified by Experts

The correct Answer is:
A
`I = 10 A, I_(g) = 10/500 A`
`S = (I_(g)/(I- I_(g))) R`
`=[(1//50)/(10 - 1//50)] xx 500 = 1 Omega` in parallel.
