A milli-ammeter of range `10 mA` and resistance `9Omega` is joined in a circuit as shown in the figure. The meter gives full scale deflection, when circuit in the main circuit is `'I'` and `A` and `D` are used as terminals. The value of `I` is

`1.09 A`

`10.9 A`

zero.

`0.109 A`

Text Solution

Verified by Experts

`(0.1+0.3+0.6)i_(1)=(9+0.9)xx10`
`i=99mA`
`I=(99+10)mA=0.109A`
