Welcome to the module on Electricity.

At the end of this module you should:
 
1. Be able to classify materials as conductors or insulators. 
2. Be able to measure current, potential difference (voltage) and resistance. 
3. Understand the relationship between current, potential difference and resistance. 
4. Be able to perform simple calculations based on the relationship between current, potential difference (voltage) and resistance. 
5. Understand the heating /chemical/magnetic effect of an electric current and identify everyday applications of these, including the action of a fuse. 
6. Understand simple series and parallel circuits containing a switch and two bulbs.
