How do i solve this? I wasn't given any examples at all. But I've tried to do this.
Iab + Iad = Ibc + Idc <--------- they have to or else Kirchoff's law violated.
so Vab = Vad but I'm not sure if Vbc = Vdc?
i'll continue assuming Vbc = Vdc
Vab/40 + Vad/20 = Vbc/70 + Vdc/50
Va=0.45714286 Vc
Vbd/60+ Vc/50 = Va/20
Vbd = 0.1714286Vc
i thought that Va + Vc + Vbd = 20
solved for Vc and i got Vbd as 2.105263 V
The answer is 0.94V. Obviously i got something wrong here. Can some one explain to me where I went wrong, and how i can fix this. Thanks
