To receive full-credit, you must show your work for all complex number manipulations. 1. The circuit shown below is driven by a current source of the form ig(t) = 25 cos(50,000t) mA. Please do the following: a) Draw the equivalent frequency-domain (i.e. phasor domain) circuit, showing the impedance of each element. b) Determine the combined impedance of the entire network. c) Determine the phasor for the voltage vo. d) Determine the time-domain expression for the voltage (i.e. find Vo cos(wt + )). e) By how many microseconds does vo lead ig 100 Ω w + 4 mH 80 nF 500 Ω Vo
