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

The correct Answer is:
D
d. `(0.1 + 0.3 + 0.6)i_1 = (9+0.9) xx 10`
`i = 99 mA`
`I = (99+10) mA = 0.109 A` .
