Problem

A transformer winding delivers a sinusoidal voltage of 9.0 V9.0\,\mathrm{V} rms at 60 Hz60\,\mathrm{Hz}. It feeds a single ideal diode (no voltage across it when conducting, no current through it when blocking) in series with a load resistor R=45 ΩR = 45\,\Omega. There is no smoothing capacitor, and the winding's own resistance is neglected. Sketch the voltage across the load against time for two cycles of the supply, marking the zero line, and from your sketch state: ((a)) the peak voltage across the load; ((b)) the time between one crest of the output and the next; ((c)) the mean output voltage; ((d)) the mean current in the load.
