2. An LRC ac series circuit has R= 15 2, L= 25 mH, and C= 30 uF. The circuit is connected to a 120-V (rms) ac source with frequency 200 Hz. a) If the rms current flowing in the circuit is 7.25 A, what is the average power dissipated by the circuit? b) If the same voltage source was hooked up only across the resistor, what would the power dissipated be? Notice that this value is larger...having the inductor and capacitor in the circuit lowers the power output because the circuit is not being run at its "resonant frequency".
