4.71 a full-wave rectifier circuit with a 1-k! load operates from a 120-v (rms) 60-hz household supply through a 6-to-1 transformer having a center-tapped secondary winding. it uses two silicon diodes that can be modeled to have a 0.7-v drop for all currents. what is the peak voltage of the rectified output? for what fraction of a cycle does each diode conduct? what is the average output voltage? what is the average current in the load?
