Circuit Review of Exit Ticket

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

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

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

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

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

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
