Question 2.a An ac power supply with VrMs =240 V and a full-wave rectifier are used to generate a de voltage for a resistive load with resistance value of 100 Q. The filter capacitor connected to the rectifier has capacitance value of 500 µF. The frequency of the ac supply is 50-Hz. a. Determine the de voltage and ripple factor at load side? Question 2.b Assume that by using an RC filter circuit, you wanted to reduce the ripple factor to half the amount that you calculated in part 2.a, answer the following questions: b. What values would you suggest for resistor and capacitor of the RC circuit? с. What is the voltage regulation of this circuit?

Consider the full-wave rectifier circuit shown below, where• vS(t) is a sinusoidal signal with a peak value (Vs = 5 V).• Diodes are modelled using constant voltage model with VDO = 0.7 V• The ac line voltage has an rms value of 120 V and a frequency (f) = 60 Hza) Calculate the transformer turns ratio.  b) Plot in the same graph signal vS(t) and the output signal vO(t) versus time (t) (show all details including amplitudes, time instances, etc.) c) Calculate the rms value of the output signal vO(t). (hint: sin2(x) = 0.5(1- cos(2x)))  d) If a capacitor C=3.58 F is connected across R = 10 k, repeat (b) in a new graph
