A 13.1-Ω resistor, a 9.57−μF capacitor, and a 15.2-mH inductor are connected in series with a 135−V generator. (a) At what frequency is the current a maximum? (b) What is the maximum value of the rms current? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise. (a) Number Units (b) Number Units
