Resistance is linear; capacitance/inductance operate in the 'imaginary' plane.
What would a third plane be to a signal?
What would a third plane be to a signal?
An electronic signal is just a voltage or current or both changing over time. The complex numbers that represent resistance and capacitance/inductance are just convenient ways to compute the frequency response of a circuit in the Fourier domain, i.e. without solving differential equations -- algebra is usually easier than calculus, in this case.
Despite all the fancy complex number math, it's still some 1D signal s(t) going through a circuit, you can watch it on an oscilloscope over time.

Not really. In recent years, hyper-complex numbers have been found to be a useful way of representing polarization.
