average power

Consider the circuit described in Problem 9.78.

a) What is the rms magnitude of the voltage across the load impedance?

b) What percentage of the average power developed by the practical source is delivered to the load impedance?

Problem 9.78

A series combination of a 60 Ω resistor and a 50 mH. inductor is connected to a sinusoidal voltage source by a linear transformer. The source is operating at a frequency of 400 rad/s. At this frequency, the internal impedance of the source is  The rms voltage at the terminals of the source is 75 V when it is not loaded. The parameters of the linear transformer are   

a) What is the value of the impedance reflected into the primary?

b) What is the value of the impedance seen from the terminals of the practical source?
