Calculate the equivalent admittance Y, for the network in Fig. the current I if Vs = 60/45° V. Example parallel circuit. Vs + ZR=292 Z = j4 Ω and use it to determine

A 300 Ω resistor is in series with a 0.140 H inductor and a 0.600 μF capacitor. A. Compute the impedance of the circuit at a frequency of f1 = 500 Hz and at a frequency of f2 = 1000 Hz. I already solved A:  Z1 = 310, Z2 = 680 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 Hz  D. State whether the source voltage lags or leads the current at a frequency 1000 Hz

Please solve thank you. No chegg solutions should be posted.
