A voltage source given by v=100sin(754t) is connected in series to a 20(ohms) resistor, a 0.1x10^-6 uF capacitor and 4x10^-3 henries inductor.
(a.) What is the frequency of the source?
(b.) Calculate impedance Z at this frequency
(c.) What is rms current?
(d.) Assume source frequency can be varied. What is resonance frequency of the RLC series circuit?
