Oh okay, I think I get it. Normally the direction can be determined if the armature is drawn slightly turned. I assumed the 'front' and 'back' labels were written as part of the answer, I guess they were originally given. Thanks.

Thank you.

YES, if you read the thread you'd see I already figured out the current. I'm asking for voltage. What are the SPECIFIC voltages of V4 and V7?

Just to make sure, V2=20v and what are V4 and V7?

Yes, I understand that. Please, I'd like to see the actual values.

Yes, I understood all that except how voltage doesn't flow. Thank you. But I'd still like to know the unknown voltage values- I understand the concept, I just can't apply it to the diagram. Odd, because I normally find these things pretty easy. V2=20v, V4=2.5v, V7=2.5v. Right? Then what?

40A. Which means I5=40A, I4=10A, I3=40A, and I6=50A. I think I knew that before. I'm mainly having trouble grasping the voltages.

Er. I'm not sure. I'm sorry, but I'm not good at learning by having people tell me what to do. Could you tell me the unknown values in only the first diagram? Then I can see the values and the pattern. That's what I normally do.
