Kirchhoff law problem and equivalent resistance

1. using Kirchhoff law find the current in following branch

answer   AB:(5/8) A, CA: (5/2) A, DEB: (15/8) A

AD: (15/8) A, CD: 0 A, BC: (5/2) A

2. using Kirchhoff law find the current in following branch 

Answer current in branch AB= (4/17) A

In branch BC = (6/17) A

In branch CD = (4/17) A

In branch AD= (6/17) A

In branch BD = (-2/17) A

Total Current =(4/17) +(6/17)+(-4/17)+(6/17)+(-2/17)=(10/17) A

4. find R Equivalent
