1. Circuit Review of Exit Ticket

2. The correct answer is d
We know this is a parallel circuit because there is more than one route for the electrons (current) to take

3. The correct answer is a
The reason the answer is a is because it is a parallel circuit, therefore a switch at 2 would only turn off the first light bulb and a switch at 3 or 4 would only turn off the second light bulb

4. The correct answer is b
This is the correct answer because we need to complete the series circuit reconnecting the light bulb to the battery

5. The correct answer is d
All circuits must contain a wire, a load, and a source of emf

6. The correct answer is a
In a series circuit, if one load is broken/disconnected then all loads go out

7. The correct answer is d
We learned that batteries are powered by chemical reactions, which in turn power the electrical energy, which is used to shine the light
