Question

A resistor and capacitor are connected in series across an ac generator. The voltage of the generator is given by V(t) = V0 cos(?t), where V0 = 120 V, ? = 120? rad/s, R = 300?, and C = 4.5?F. (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? a. The magnitude of the impedance is ?. b. The amplitude of the current through the resistor is mA. 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.)
