We are learning about superposition and I understand the basic concept, I have been calculating the currents and voltages marked out on this page, why would the signs be opposite for I1, is it the direction of current flow? I thought if the current source has become open circuit the current would have to flow into the node from V through the first 4 ohm resistor. Can anyone advise how best to understand this type of problem,
Thanks,
Keith
