(a) What is the resonant frequency of an RLC series circuit with R = 20 Ω , L = 2.0 mH , and C = 4.0μF ? (b) What is the impedance of the circuit at resonance?

A resistor and capacitor are connected in series across an ac generator. The voltage of the generator is given by V(t)= Vo cos(wt), where Vo 120 V, w = 120m rad/s, R= 6000, and C= 6μF. (a) What is the magnitude of the impedance of the RC circuit? (b) What is the amplitude of the current through the resistor? (c) What is the phase difference between the voltage and current? Hint a. The magnitude of the impedance is b. The amplitude of the current through the resistor is c. The phase difference between the voltage and current is rad. (Take the positive phase difference to mean that voltage is leading the current by this phase difference.) Submit Question Q. mA, MacBook Pro
