A 120 ohm resistor is in series with a 0.140 H inductor and a 0.500 micro F capacitor.
a) Compute the impedance of the circuit at a frequency of f1 = 500 Hz and at a frequency of f2 = 1000 Hz.
b) In each case, compute the phase angle of the source voltage with respect to the current.
c.) State whether the source voltage lags or leads the current at a frequency 500 {\rm Hz}.
d) State whether the source voltage lags or leads the current at a frequency 1000 {\rm Hz}.
