* Cells are energy storage devices. They contain chemical energy that can be converted into electrical energy.
* Circuits need a power source. To power lights and motors, you need a continuous flow of electrical energy.
How it works:
1. The cell (battery) stores chemical energy. This energy is released as electricity when the cell's terminals are connected in a circuit.
2. The circuit provides a path for the electricity to flow. This path includes the lights, motors, and any other components connected to the circuit.
3. The electricity flowing through the circuit powers the components. Lights turn on, motors rotate, etc.
In summary:
* A cell is a storage device that converts chemical energy to electrical energy.
* A circuit provides a path for this energy to flow and power components.
Think of it like this:
* The cell is like a fuel tank containing the energy.
* The circuit is like the engine and pipes that use the fuel to make the car (the components) run.
