In today's A Level Physics revision question we try an electrical circuits question on electricity.

This is a question on electrical circuits and internal resistance from Edexcel A Level Physics but it is also highly applicable to any other exam board including OCR A Level Physics, AQA, WJEC, Eduqas and similar courses such as IB Physics, AP Physics etc.

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

For official solutions check out the Edexcel Pearson website: qualifications.pearson.com/en/qualifications/edexcel-a-levels/physics-2015.html
