In Fig. 4 (a) a surface plot of the energy coefficient m from equation (25) vs. ε and p is shown. A value of m > 1/2 is possible for low values of p (p→0) and large values of ε (ε→1).Another plot of m versus ε and p, for α = 0.75, is shown in Fig. 4 (b) where one can clearly see that m > 1/2 is also possible and even in a wider range of ε and p.
Sinusoidal Steady-State Power Calculations
The power at the terminals is continually exchanged between the circuit and the power source driving the circuit at a frequency of $$2omega .$$ What this means, is that when p is positive, energy is stored in the magnetic fields associated with the inductive elements, and when p is negative, energy is being removed from the magnetic fields.
