The figure below shows a load resistor that has a resistance of RL = 22.0Ω connected to a high-pass filter consisting of an inductor that has inductance L = 3.20-mH and a resistor that has resistance R = 4.00Ω. The output of the ideal ac generator is given by Epsilon = (100 V) cos(2θft).
(a) Find the rms currents in all three branches of the circuit if the driving frequency is 550 Hz.

(c) Find the fraction of the total average power supplied by the ac generator that is delivered to the load resistor if the frequency is 550 Hz.
(d) Find the fraction of the total average power supplied by the ac generator that is delivered to the load resistor if the frequency is 1890 Hz.
