- 01
Light the bulb.
You need a battery, a closed switch, and something in the gap that lets electricity through.
- 02
Light it using only one battery.
It will work, it will just be dim.
- 03
Make the bulb brighter without changing the object in the gap.
Add another battery.
- 04
Make it as bright as it will go.
Three batteries in a row.
- 05
Turn the bulb off using only the switch.
Leave the battery and the conductor exactly where they are, and open the switch.
- 06
Turn the bulb off a second way, without touching the switch.
Put something in the gap that does not let electricity through.
