![]() ![]() ![]() Resistance of a component can only be measured for components that aren’t already in a circuit. ‘Resistance is a measure of how difficult it is for electrons to flow around a circuit. They might like to write the information shared throughout this activity on the back of their sheets: Share this information with the group.Give out copies of the ‘Multimeter diagram’ sheet to everyone taking part.Changing components, like resistors, should change the circuit values. Use crocodile clips and terminal blocks to temporarily make circuits.Bear in mind that when using a 9V (volt) battery, any resistors used should be at least 100Ω (ohm) and that an appropriate current-limiting resistor (at least 330Ω) must be used for any circuits containing a light-emitting diode (LED).There are also lots of handy step-by-step videos on the internet (including ‘how to’ guides) about multimeters. This is a good opportunity to invite an expert along to share their knowledge with the group.You could save on circuits and multimeters by running this activity as a base, with groups taking turns to complete the tasks. ![]() The circuits could be borrowed or reused from other sessions. You will need some ready made circuits to test, either have some circuits ready or have all the components and equipment needed to make some. ![]()
