Variable resistance
Publication Date:
June, 2014
Type of Resource:
Practical activity/investigation
A downloadable resource to help teach about variable resistors.
The resource is a student practical activity where students examine the properties of variable resistors by making one of their own.
In the activity, students create a variable resistor using a shaded-in 'box' drawn with a 'lead' pencil (graphite really) and use it in series with a Light Emitting Diode (LED) to control the amount of light emitted by the LED.
The document contains student instructions and questions to answer.
Teacher notes are provided on page 2 of the document.
