Note the sources are given in RMS units 1 0.25 F 1 5 2 0.5 F 10 sin (t+30) Arms v O + + 4 cos (t) Vrms 10  + 2 cos (t) Vrms (a) [5 points] Convert the circuit to the frequency domain label each element. 1 Print Your Name___________________________________________ (b) [15 points] Using any method you like, solve for the voltage, V O . (c) [5 points] What is the time domain voltage v O (t). Give the real part only. 2 Print Your Name___________________________________________ Problem 1 continued. (d) [15 points] Find the average power and the reactive power delivered by each source and absorbed by each impedance. Tabulate your answers below. Element P Q 1 ohm 5 ohm 10 ohm 1 Henry 2 Henry 0.25 Farad 0.50 Farad 10 sin(t+30) Arms 4 cos t Vrms 2 cos t Vrms 3 Print Your Name___________________________________________ 2. [10 points] Consider the unknown impedance below. You are given that the current leads the voltage by 30. Will the reactive power absorbed by this element be positive or negative? Will the reactive power absorbed by this element be positive or negative?...
