Auto mechanics Paper 2 WASSCE (PC 2ND), 2018

Question 2

 

(a)        Identify the three electrical symbols shown below:

 

(b) (i)  Sketch a simple circuit from the three electrical symbols shown in 2(a).

   (ii)  State what happens when the circuit is closed.

(c)  Explain each of the following:

  1. conductor;
  2. insulator.

Observation

 

Candidates who attempted this question faired well in parts (a) and (c) of the question.  Part (b) was poorly responded to.  The required response to part (b) is:

(b)  (i)  Simple lamp circuit

                       

                                                                                   
(ii)       When the circuit is complete, the light glows.
OR

When the switch contacts are closed, current flows and there will be light.
