Maximum Power of a Cell - OCR PAG 3.3 PRACTICAL - A Level Physics

In this video I go through an OCR Physics A Level Required Practical that investigates the maximum power of a cell. (This is the OCR PAG 3.3 practical.)

Once you have taken measurements for current and potential difference as a cell is connected to circuits with a changing amount of resistance, you can then work out the power of the cell and plot how this changes as the resistance of the external circuit increases.

Thanks for watching,
