SC 9) (5 marks) Figure 9 represents a simple circuit in the time domain. The impedance of a capacitor in the complex frequency domain is Z = 1 and for an inductor Z = sl. If the complex frequency describing the circuit in Fig. 9 is s = -150 +j100 s-1, determine the time domain voltage vs(t) (provided by the source) which corresponds to a frequency-domain voltage V2 = 52-250 V. i(t) 21 12 + V1 + Vs 100 mH...
