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
- Testing electronic circuits and control systems is often referred to as fault finding.
- A multimeter is used to measure current, voltage, resistance in both virtual and physical circuits and control systems.
- Resistance and voltage are measured in parallel but current is measured in series.
- Virtual and physical test results will differ due to the tolerance of physical components and test equipment.
Keywords
Multimeter - an electronic tool that measures voltage, current and resistance
Voltage (V) - the measure of the ‘push’ from a battery that causes charge to be transferred around a circuit
Current (A) - the rate of flow of charge in a circuit
Test - check quality, function and reliability
Common misconception
Testing must always be done using a physical control system.
Testing a control system can be done using a physical control system and a multimeter or using a CAD simulation.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
