(12 points) In the circuit below Vac is the power outlet voltage in North America: 120 Vrms @ 60 Hz. The forward bias diodes Ds1 and Ds1 are represented as a constant voltage drop VD)=0.7 V, CF1=1280μ F, CF2=1300 μF, the LEDs are also represented using a constant voltage drop of VLED-2 V, Rg1 = Rg2=470 92, RL1-136 2, and RL2=152 $2 a. Calculate the average voltage at terminal VPos. b. Calculate the ripple voltage at terminal VPos. c. Calculate the average voltage at terminal VNeg. d. Calculate the ripple voltage at terminal VNeg. Tip: Use the Thévenin equivalent circuit after the capacitor to calculate the load current. Note: In this problem, you may only submit numerical answers accurate to 0.02% or better. (i.e. If 4 is the correct answer, 3.9999 will be marked as correct, but 2+2 will be marked as incorrect. ) 2 Vac No connection!
