Welcome to the module on Electricity.

Things to note!
 
1. The classification of materials into conductors or insulators. 
2. How to measure current, potential difference (voltage) and resistance. 
3. The relationship between current, potential difference and resistance. 
4. Calculations based on the relationship between current, potential difference (voltage) and resistance. 
5. The heating /chemical/magnetic effect of an electric current and identify everyday applications of these, including the action of a fuse. 
6. The simple series and parallel circuits containing a switch and two bulbs.
