Circuits and Systems II Hayder Radha - 2 - ECE 202 [1] Equivalent Impedance at 60Hz Let the voltage source () s vt be a sinusoidal function with a frequency 60Hz f = , phase angle o 0 φ = , and amplitude 100V V A = : ( ) ( ) 100cos 2 (60) s t π = . (a) Evaluate the equivalent impedance Z of the above circuit at steady-state. (Here, we are evaluating the equivalent impedance Z at f = . Note that the amplitude and phase angle of the source voltage do not impact the equivalent impedance Z .) (b) Derive the expression for the output voltage () out
