Observation

      The expected answers were;

(a)        (i) Name of each part lettered A – F
A – earth/ground                    
B – battery/cell                      
C – switch                              
D – coil                                  
E – distributor                        
F – plug/spark plug/capacitor/condenser

(ii) Function of each part lettered A – F
A – Completes the circuit of the ignition system.                                                     
B – Supplies the current/voltage/power/initial current needed by the system.         
C – Put on/connect and off/disconnect the supply from the battery to the coil.        
D – Transforms voltage to the value required to produce spark at the plug gap and ignite the mixture in the combustion chamber/steps up battery voltage.                     
E – Distributes/channels/share/step-up the current in the system to all the plugs.    
F – Ignite the mixture in the combustion chamber/produce spark needed to start the engine.                                                                                                                                               
(b) Function of the ignition system in a motor vehicle
It amplifies the battery voltage and distributes it to the plugs in turns.      

It was reported that only a few candidates attempted Question 3 and majority of those who attempted it did not respond well. They showed poor understanding of ignition systems. Teachers are encouraged to emphasize this area of the syllabus during instruction.
