1) A series RLC ac circuit is at resonance. It contains a resistor of 30 Ohms, a capacitor of 0.35 microFarads and an inductor of 90 mH. If an effective (rms) voltage of 150 V is applied, what is the peak current?
2) An AM radio turning circuit has a coil with an inductance of 6.0 mH and a capacitor set at 7.5 x 10-6 microFarads. What frequency will it detect?
