Question 7

 

 

Draw the output for the circuit diagram illustrated above.    

 

Observation

 

Candidates performance was poor. Most candidates either had incorrect idea or no idea at all about the output wave form for the circuit diagram. Rectification should be treated better in schools. Also, schools should be encouraged to own oscilloscopes. Performance was low

 

The expected answer is

Diagram of output waveform of circuit diagram
