WebOct 12, 2024 · Thus the field current is much less compared to the armature current. From the circuit, the current and voltage equations are, Input current, Current through field winding, Back emf developed, Power drawn from the supply, P = VI. Mechanical Power developed, P m =Input power – Losses in the armature and field winding. WebTo determine the parallel reactance, we use Equation 3, so. So XP2 = 21.21 Ω. If we wanted to, we could replace XS2, XP2, and the 2.1 Ω resistor with a single parallel resistor equal to 212.1 Ω and the circuit would present the same impedance to the source at 100 MHz. This can be simulated in LTspice.
