Use the diagram of the electric circuit and the given current to find the total impedance for the circuit and the voltage of each current. How do I start? @jim_thompson5910.

    I get it now. Kind of, but it's clear to me.

    You need to find the resistor, inductor, and capacitor.

    in 19, it looks like they don't have an inductor, so we'll toss that out |dw:1442456699559:dw|

    I get how they found 4-2i now. It's easy, but the problem on my homework is not clear on some of the components.

    based on the rules you posted, I'm getting 1 - 3i

    the inductor is missing.

    so I think you put 0+0i for that

    the inductor is 2.

    the inductor isn't put in the drawing for #19

    oh you're supposed to find the inductor first?

    yes, but I was looking at the example and thought I can follow the rules as that one, but I don't know what to do honestly.

    hmm idk how to find the inductor first

    I think we don't need it, because the answer is suppose to be like 4-2i. And we can leave it alone.

    which is why I'm still thinking it's 1-3i |dw:1442457218231:dw|

    I still don't know what to do with the missing inductor. Maybe just ignore it?

    then to compute voltage, you use V = I*Z in this case, I = 12+36i (given current) Z = 1-3i (what we just found)

    There is voltage too.
