Actually im not all to sure myself exactly how the numbers ended up complex. I don't recall any sqrt( - numbers)


Apparently inductors and capacitors in circuits result in complex numbres.
Something about being 90 degree's out of phase with the rest of the circuit.

and that makes them complex I guess.


i'ts like resister resistance + capacitor reactance


100 ohms + j100 ohms. and in electronics we use j instead of i for complex numbers.

and we do polor notation.
141.42 ohms at angle 45 degree's.
