ELECTRICITY Section 2: Introduction to electrical circuits and how to draw them, circuit symbols, series and parallel circuits
Sub-index for electricity section 2 notes on electrical circuits 2.1 Definitions: what is an electric current? what is an electrical circuit? 2.2 Circuit symbols and drawing-constructing circuit diagrams 2.3 Examples of simple circuits and their interpretation 2.4 More examples of comparing simple circuit diagrams (may involve some simple current deductions) 2.5 More complex bulb circuits and deducing the current flowing (involves some simple current calculations) See also overlapping Parts 1.1 Important definitions, descriptions, formulae, units for electricity 1.6 Power, energy transfer & electricity cost calculation QUESTIONS See Electricity section 3 for more problems to solve involving the V = IR, Q = It and E = QV calculations equations for exam practice It is better to be able to rearrange a formula rather than using a triangle Basic QUIZ on "Electricity and Magnetism" Basic revision questions from UK KS3 science-physics (~US grade 7-8)on simple circuits, circuit symbols and components, current flow and ammeter readings, useful circuits, hazards and how they work, magnets and electromagnets - what have you remembered from before GCSE physics?
