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

A

`1.09 A`

B

`10.9 A`

C

zero.

D

`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`
