Making a Resistor

Making a Resistor

A practical I do with my year 9 group (but could be adapted for GCSE). We make a basic variable resistor by shading in an area on grid paper using graphite pencils. Then see how resistance is affected with length. I originally got the idea from a video clip I saw on YouTube, the link is attached here. You will need to have digital multimeters to do this, that have a setting to measure resistance. NB: I'm a recently qualified teacher, so constructive comments on my resources and how they can be improved are really welcome! So please leave a comment if you used them! Thanks!

Resistivity/Resistance investigation - Length vs. Resistance of pencil graphite

Resistivity/Resistance investigation - Length vs. Resistance of pencil graphite

I made a PowerPoint a few years back on how to make a resistor with pencils. Here are (differentiated) instructions explaining to students how to carry out the investigation. Included is the original publisher file if you want to edit it. If you don't have publisher a PDF is also included! To do this experiment you will need a digital multimeter that can measure resistance.

Transformer experiments - For non-specialist physics teachers

Transformer experiments - For non-specialist physics teachers

Attached is everything you will need to teach a lesson (with a class practical or demonstration) on transformers. Using a multimeter that can measure AC voltage (available at places like Maplins), and a set of transformer coils (available from Phillip Harris) students measure the voltage across the primary and secondary coil of a transformer. Included are student instructions, guided questions, and teacher set up instructions. PLEASE MAKE SURE YOU HAVE A MULTIMETER THAT CAN MEASURE AC VOLTAGE BEFORE PURCHASING! See cover image for all equipment you will need!
