Looking at Circuit 3 more closely, I can see:

- There are two batteries shown
- One battery has a wire connected to one terminal of the light bulb
- The other battery has a wire connected to the other terminal of the light bulb
- However, there's no connection between the two batteries themselves
- For a complete circuit, electricity needs to flow from one terminal of a power source, through the components, and back to the other terminal of the same power source

In this case, the circuit is incomplete because:
1. The two batteries aren't connected to each other
2. The light bulb is connected between the two separate batteries, but there's no return path for the current

This creates an open circuit, so electricity cannot flow.

Final Answer:
1. Will NOT light (switch is open)
2. Will light (complete circuit)
3. Will NOT light (incomplete circuit - batteries not connected)
4. Will light (complete circuit)
5. Will light (complete circuit with two bulbs in series)
6. Will light (complete circuit with two bulbs in series)
