F = 2 / 3.14 = 0.6369 kHz. = 637 Hz. R = 4,000 Ohms. L = 23 h. C = 33 uF. Xl = 6.28*636.9*23 = 91994 Ohms. Xc = 1 / (6.28*637*33*10^-6) = 7.58 Ohms. tanA = (Xl-Xc) / R = 91986 / 4000 = 23. A = 87.5 Deg., Inductive. Therefore, the current lags the voltage by 87.5 Deg.

a. L = 33.0 mH = 0.033 H. Xl = 2.2 k. Ohms = 2200 Ohms. Xl = 2pi*F*L = 2200 Ohms. F = 2200 / 2pi*L=2200 / (6.28*0.033h) = 10,616 Hz. b. C = 1/(2pi*F*Xc). C=1 / (6.28*10616*2200)=6.818*10^-9 F.= 0.00682 uF. c.Xl = 3 * 2200 = 6600 Ohms. d = Xc = (1/3)*2200 = 733.3 Ohms.
