A student is asked to design a circuit by which a direct voltage of peak value 
is obtained from a 
alternating supply. The student uses a transformer that may be considered to be ideal and a bridge rectifier incorporating four ideal diodes. The partially completed circuit diagram is shown in the figure below.
On the figure above, draw symbols for the four diodes so as to produce the polarity across the load as shown on the diagram.
Calculate the ratio
or 
or 0.027.
