Question 4

 

         The circuit diagram below is simple current rectifier circuit. Use it to answer the questions that follow.
        
(a) State the function of each of the parts labeled A and B.

(b) Sketch the output signal produced.

Observation

 

This question was unpopular among candidates and the performance of the few that attempted it was poor.

The expected answer

                     (a)        Function of Parts Labelled

A         -           produces the alternating current (a.c)            
B         -           smoothens the rectified current                     

                     (b)        Output Signal
