- In the water circuit the water wheel is the limiting factor. The larger
- the load on then wheel the slower the flow round the circuit. In the
- electrical circuit it is the lamp that is the limiting factor. We call this
- limiting factor resistance. You can learn more about this in the
- "Resistance in Circuits" topic.
