Student and teacher workbook on the following topics: 1. Electric current 2. Heating and fuses 3. Mains electricity 4. Voltage and resistance 5. Voltage and current 6. Resistance 7. Electric light 8. Electrical heating
Activities include: • a discussion about electrical circuits to reinforce knowledge and highlight misconceptions • students look at how current flows in series and parallel circuits • how the flow of current is affected by resistors • setting up circuits and drawing circuit diagrams • an introduction and demonstration on the use of multimeters.
Activities include: • demonstrating resistance in an electrical circuit • defining and calculating resistance • investigating the voltage and current characteristics in a constantan wire • Ohm's law and ideas of ohmic and non-ohmic behaviour • student calculations (and answers) with currents given in amps, milli-amps and micro-amps
The activities are: • combining lamps in series and parallel • deriving formulae for series and parallel resistance combinations • worked examples of resistors in a circuit • predicting and measuring resistance • practice calculations with answers provided
