Explanation / Answer
switch closed
let
a in first branch bottom to top, dividing b in second top to bottom and (a-b) in third top to bottom
kirchoff law
2a-6+9+4b=0
2a+4b=-3...1
2a-6+5(a-b)=0
7a-5b=6....2
solving we get
a=-0.868
b=-0.316 amp
part a:0.868 amp top to bottom ...(-ve so -bottom to top =top to bottom)
partb:0.316 amp bottom to top...(-ve so -top to bottom =bottom to top.)
switch is open:
part c and part d
i=(9-6)/(2+4)=3/6 =0.5 amp...[both batteries have same face together,so difference]
part c:0.5 amp
part d:0.5 amp
