AKASH Question

I'm getting a weird answer.... -24 V??

34/9 ??

Release i₁ from 4V bater in anticlockwise,i₂ from 6V battery in clockwise

4-8(i₁+i₂)-6i₁-2i₁=0
=> 4=16i₁+8i₂ ----------(1)

and 6-4i₂-8(i₁+i₂)-1i₂=0
=> 6=8i₁+13i₂ -----------(2)

SOlving we get i2=8/18
i1=1/36

V_A=A_D
V_D-8(i₁+i₂)=V_C
V_D-V_C=8(i1+i2)
V_D-V_C=34/9

there may be some caculation mistakes..but method will be same [1]
