Expert Answer
By applying Kirchoff's voltage law to the top loop ' acdba ' , we get
-2 
2 - 4 + 3 1 = 10 or 3 1 - 2 2 = 14 ............................. (1)
2 - 4 + 3 1 = 10 or 3 1 - 2 2 = 14 ............................. (1)By applying Kirchoff's voltage law to the top loop ' cefdc ' , we get
- 3 - 3 1 = - 4 or 3 1 + 3 = 4 .............................(2)
3 - 3 1 = - 4 or 3 1 + 3 = 4 .............................(2)At node d , if we apply Kirchoff's Current law , we get
1 + 2 = 3 ....................................(3) By substituting 3 using eqn. (3) , we rewrite eqn.(2) as
3 using eqn. (3) , we rewrite eqn.(2) as 4 1 + 2 = 4 ..................................(4)
1 + 2 = 4 ..................................(4)By solving eqn.(1) and eqn.(3) , we get , 1 = 2 A and 2 = -4 A
1 = 2 A and 2 = -4 A From eqn.(3) , by substituting 1 and 2 , we get 3 = -2 A
1 and 2 , we get 3 = -2 A
