have varying phases as well as varying magnitudes of impedance. For example, the formula for a wire
with skin effect is:
EWIRE A 4a LAPLACE {I(VSENSE)}={R0 + R1*sqrt(s)}
VSENSE 4a B
The wire's impedance is constant (and real) at low frequencies. At high frequencies, its impedance
behaves as the square root of the frequency and becomes half real and half imaginary (that is, it
becomes half inductive).
