Homework Statement
1) Q. Which of the elements follow the passive sign convention? (psc)
[PLAIN]http://img401.imageshack.us/img401/3092/pic1r.gif
v1 = +5 (V)
i1 = +2 (mA)
v2 = -10 (V)
i2 = +500 (µA)
v3 = +1 (V)
i3 = -3 (mA)

2. The attempt at a solution
For number 1, I said elements 1 and 3 follow the psc, because the current is moving from the + end to the negative end.
And number 3 is same as number 1, except the +/- signs change for the number 3. I feel like you have to do something like KCL or KVL to figure out the actual flow of those currents. After figuring out the actual flow of the current (the reference marks may be right or wrong), then you sort of determine which elements follow the psc.
So I'm not sure if my initial stab at the problem is actually right( which I highly doubt ><). and if isn't right, then I don't know how else to determine the psc for these elements.
