- A light bulb is a kind of electrical device
- An electrical device requires electricity to turn on
- Therefore, a light bulb requires electricity to turn on

- An electric circuit is a vehicle for moving electrical energy from the source to the electrical device
- When a switch in a simple series circuit is closed , electricity will flow through the circuit
- Therefore, when a switch is closed, the electrical energy will flow from the source to the electrical device

- When a switch is closed, the electrical energy will flow from the source to the electrical device
- A light bulb is a kind of electrical device
- So, when a switched is closed, the electrical energy will flow to the light bulb

- When a switched is closed, the electrical energy will flow to the light bulb
- Electricity is a kind of electrical energy
- Hence, when a switch is closed, the electricity will flow to the lightbulb

- A light bulb requires electricity to turn on
- When a switch is closed, the electricity will flow to the lightbulb
- So, when electricity flows to a light bulb , the light bulb will turn on / come on

So, when electricity flows to a light bulb , the light bulb will turn on / come on
Question: When the switch in a simple series circuit is closed, what happens to the light bulb that the electricity is flowing to?
