Distinguish between a parallel and series circuit.
A series circuit lets electricity flow along one path only. A parallel circuit lets electricity flow along multiple paths.
In which circuit will two or more bulbs be brighter and why?
A parallel circuit. This is because each bulb gets the whole amount of power from the battery as each bulb has its own path.
In a series circuit with 3 bulbs, what happens if one bulb is unscrewed and why?
They all go out because the circuit is broken.
In a parallel circuit with three bulbs, what happens when you unscrew one bulb and why?
Only that bulb goes out because the other bulbs are still connected via their own individual paths.
What happens to the brightness of bulbs in a series circuit as more bulbs are added and why?
The bulbs will grow dimmer and dimmer as each bulb is added. This is because they all share the same battery power.
What happens to the brightness of bulbs in a parallel circuit as more are added and why?
The bulbs maintain the same brightness and are equally bright. This is because each bulb has its own circuit and is connected directly to the battery.

What is the difference between an open circuit and a closed circuit?
Open circuits do not let electricity through whereas closed circuits do.
