Answer 1

V = 120 v rms, theta = 0 degree, f = 60 Hz X_L = 2 pi f_L = 2 pi (60) (50 times 10^-3) X_L = 18.85 Ohm X_C = 1/2 pi f_C = 1/2 pi (60) (1 times 10^-6) = 2652.582 Ohm I_T = 120 angle 0 degree/1000 - j2652.582 + j18.85 I_T = 42.59 angle 69.2 degree mA S = VI_T* = (120) (42.59 times 10^-3 angle (69.2))* S = 5.11 angle -69.2 degree VA I_T = 42.59 angle 69 degree mA 4. F = 60 Hz X_C = 1/2 pi f_C = 1/2 pi (60) (100 times 10^-6) = 26.525 Ohm X_L = 2 pi f_L = (2 pi) (60) (100 times 10^-3) = 37.699 Ohm Z_T = 10 - j26.525 + j37.699 Z_T = 10 + j11.2 Ohm
