The reading of ammeter shown in figure is

A

`6.56A`

B

`3.28A`

C

`2.18A`

D

`1.09A`

Text Solution

Verified by Experts

The correct Answer is:
C
The equivalent circuit of the given circuit will reduced to as shown in the figure

Total resistance fo the circuit `=(2xx4)/(2+4)+0.8=(8)/(6)+0.8=(12.8)/(6)Omega`
Total current in the circuit= `(14)/((12.8//6))=(84)/(12.8)A`
Reading of ammeter `=(84)/(12.8)xx(2)/(6)=2.18A`
