Response to the following:
A full-wave bridge-rectifier circuit with a 1-kΩ load operates from a 120-V (rms) 60-Hz household supply through a 12-to-1 step-down transformer having a single secondary winding. It uses four diodes, each of which can be modeled to have a 0.7-V drop for any current.
What is the peak value of the rectified voltage across the load?
For what fraction of a cycle does each diode conduct?
What is the average voltage across the load?
What is the average current through the load?
