Electricity and magnetism _Choney Duba


In this course  students will familiarized with various sources of electricity. Electricity generated from hydroelectricity, chemical cells, solar cells, fossil fuel power generators and nuclear power generators are used for transportation, factories and various purposes at home.

Students will learn to connect circuit by themselves using cells or batteries, bulbs, and conductors like copper wires. Electric current that flows through the circuit without blockage is a complete circuit. The simplest complete circuit may be demonstrated by connecting a piece of wire from one end of a battery to the other.

Students will  explore, investigate and discover that magnets attract only certain materials available on the Earth. This investigation will help them to locate the usage of magnets in their day-to-day life. They also discover many electrical appliances that work using magnets.
