🦸 Myth busters for this topic
❌ "Batteries store electricity inside them."
✅ Batteries store chemical energy, which is changed into electrical energy when the circuit is complete.
A battery is like a little energy factory that only works when it is connected in a complete loop.
Try it yourself: Connect a battery to a bulb with a switch. The bulb uses the energy only while the switch is closed.
