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:
- conductor;
- 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.
