This is the basic introduction to current flow and circuits. Really this unit is just an extension of GCSE Electricity with some harder problems using the same rules. Also you will need to remember how each component works and be able to interpret a VI graph. Always remember to check your gradient. Since V=IR a …
This section is about applying some more advanced rules to circuits that build on your GCSE skills. The trick is to realise that you must be 100% logical and treat it as a mathematical exercise. If you set up the problems correctly then you cannot go wrong. Take note of these things that you must be …
