A series circuit consists of a 1.50-mH inductor, a 125-? resistor and a 25.0-nF capacitor connected across an ac source having a peak voltage of 35.0 V and a variable frequency. At what angular frequency(ies) will the current amplitude be equal to 1/3 of its maximum possible value? At the frequency(ies) just found what are the current amplitude and the voltage amplitude across each of the circuit elements, including the ac source?
