In the lesson on circuits, a model was suggested where there was a pizza shop that made pizzas and they were delivered to a party to model how a circuit works.

Be sure to describe what represents the voltage, what represents the current, and what represents the resistance. Also: what are the limitations of your analogy? Does it fall apart as an analogy at all?
