These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Voltage, current and resistance are the key concepts when designing electronic systems.
- Input, process and output components are used to construct electronic systems.
- CAD and breadboarding are ways of modelling an electronic system in order to test it.
- Printed circuit boards are used in electronic products.
Keywords
Ohm's law - The relationship between voltage, current and resistance
Breadboard - A device used to plug in electrical components and test circuits
Polarity - The directional flow of electrons from one pole to another
Resistance - The opposition to the flow of current
Common misconception
Components all work however they are positioned circuit.
Some components are polarised and only work if they are the correct way round.
