In this video we look at a question on electricity and electrical circuits in A Level Physics on the variation of resistance.

This is a question from the OCR A Level Physics Specification but also applicable to all exam boards including AQA A Level Physics, Edexcel, iEdexcel, CIE and similar courses such as AP Physics and IB Physics.

Please note that this is not an official solution and I am not affiliated with the exam board.
