Hurrah, we come to the end of the module! We started by asking what the difference between a car and a TV remote battery was. We know that a car requires more current than a TV remote. To produce more current, the car battery must have a high potential difference.

So, the difference between the two batteries is in their potential difference (voltage). A TV remote battery has around 1.5 V potential difference. A car battery has about 12.5 V potential difference.
