Question 7

 

The circuit diagrams labelled A and B above are used to rectify alternating voltages. Sketch a graph of output voltage against time across

Observation

Candidates performance was below average. Very few candidates were able to obtain the maximum marks.
The expected answer is :

(a)Graph of output voltage against time across R1

(b)Graph of output voltage against time across R2
