    Current calculation of a Y-junction

    Thank you. I'll try to reupload the pics. This is the circuit: I did a delta-Y conversion and the new impedances are: I hope that the rest is pretty legible. Thank you, again

    Current calculation of a Y-junction

    Hello everyone! I've been trying to solve this circuit but there's something wrong. Firstly, I made a Delta-Y conversion so that1 and zA were in series, and so were z5 and zb. I really don't know if writing "I0=IA-IB" is correct, cause basically I0 is the current that flows between the nodes A...

    Single Loop Potential difference -- sign issue

    sorry but i still can't get over it... when i calculate Vab counterclokwise i go from + to -, so why should i take it positive? thank you
