In DC simulations (f = 0 Hz) the circuit property results are simple real number denoting the peak values of current and voltage, and direct values of inductance L and resistance R.

However, in AC simulations (with f > 0 Hz) the circuit property shows inductance L and resistance R as complex numbers with real and imaginary components.

For example, in the figure above at 50 Hz, the inductance L is:

Flux/Current = 0.00998433-I*2.38572e-005 Henries

and the resistance R is:

Voltage/Current = 0.183112+I*3.13667 Ohms

The meaning of these values is such that the real value of inductance (L re = 0.00998433 H) represents the actual inductance of the winding. But the imaginary part (L im = -I*2.38572e-005 H)
