Hi, I have been given this circuit but I am a bit doubtful about my problem solving steps. First of all, I have been given the magnitude and direction of i1 and i2, but not for i3 so I have guessed the direction since the current i1 and i2 meet to node B. As for the voltage source Vs, I have guessed the polarity because of the direction of i1, but I'm not sure if it is actually correct. In the last question (f) I have been asked to find the current i3, but I thought it was easier to calculate before point (e) in order to find the voltages Vs and Vb. I have then used KVL applied to the loops ADBA and loop BDCB. Could you let tell me if what I have done is correct of is there any mistake?
