Problem

A transformer winding delivering 24 V24\,\mathrm{V} rms at 50 Hz50\,\mathrm{Hz} feeds a bridge of four ideal diodes (no voltage across a conducting diode, no current through a blocking one), whose output goes straight to a resistive load of 100 Ω100\,\Omega. There is no smoothing capacitor and the winding's resistance is neglected. Sketch the load voltage against time for two cycles of the supply, marking the zero line and the mean level, and from your sketch state: ((a)) the peak load voltage; ((b)) the number of output humps per second; ((c)) the mean load voltage.
