Figure A:
How to find Branch Current?: Find Ia to e for Figure A.
How to find the Voltages? Find Vr1 to r7 for Figure A.
Given: Ia= -1.08 & VR4= 7.03

Figure B:
How to find Branch Current?: Ia to h for Figure B.
How to find the Voltages? Find Vr1 to r6 for Figure B.

Figure B: http://ppl.ug/SZrJNhJwVSI/

 

Figure A:
Ie = 18/4.2k= Ie
Ic = 18/7.71k
Ib = Ic(6.5/(6.4+5.6))
Ia = Ic(5.6/(6.4+5.6))
Id = Ic+Ie

Right?

 

One of the nice things about circuit analysis is that you can almost always check the correctness of your results. Use your results to calculate the various node voltages and branch currents and if they are consistent, then they are correct.
