Consider the diode bridge rectifier shown below with the voltage regulating capacitor in parallel with the load resistor. 60Hz 120V 10:1 C-470µF IL R₁=1kQ a) For the input signal, sketch waveforms of the output voltage with and without the regulating capacitor. b) Calculate the magnitude of the ripples at the output voltage. What is the frequency of these ripples? c) What is the current (approximately) through the load? d) What is the output voltage delivered on the load? e) If the capacitance doubles what happens to the ripples? f) If the output resistance doubles what happens to the ripples? g) If the frequency of the voltage from the wall doubles, what happen to the ripples? h) For the input signal, sketch waveforms of the current through the diodes. Do you expected to be larger or smaller from the current delivered to the load resistor? Do you expect the diodes to conduct continuously or in small time intervals?
