Cells in Series
Physics: AQA GCSE Higher, topic 2.3.4
Potential Difference
Total voltage of energy sources = total potential difference across components.

Charges as buckets of water 1
- Think of the moving charges having energy being like people carrying buckets of water.
- At the start of the journey, the buckets are filled by the energy source.

Charges as buckets of water 2
- When the people carry the buckets around the circuit they empty a little bit of water into every component that they pass.
- The people carrying the water empty water into each component so that their bucket is empty when they return to the source.
