2.27. For the magnetically coupled circuit shown in Figure P2.27, find the branch
currents and the power supplied by each source
2.28. For the magnetically coupled circuit given in Figure P2.28, determine (a)
the current through each coil, (b) the voltage drop across each coil, and (c)
the power supplied by the source.
2.29. Determine (a) the current in each branch, (b) the voltage drop across each
coil, and (c) the average power supplied by the source if the coefficient of
coupling between the two coils in Figure P2.29 is 0.8.
2.30. Coil-1 with a resistance of 0.2 and a self inductance of 20 mH is tightly
(k = 1) coupled to coil-2. The resistance and the self inductance of coil-2
are 0.8 and 80 mH, respectively. Coil-2 is connected to an inductive load
of 30 in series with a 20-mH inductance. If the rms value of the impressed
