Battery?
2 or more cells
Electrical insulator
Material that does let electricity flow through
Electrical conductor
Material that allows electricity to pass through it
Why are electrical wires made of metal?
Metal is a good conductor
What is a resistor
Reduces a current when it is too high
What’s a fuse?
A piece of wire that is designed to melt if the current gets too big
Filament?
Part of a bulb that heats up and creates light
What are the points of a series circuit
If one bulb breaks all the others go off
The current is the same everywhere
The bulbs will get dimmer depending on how many you have
What are the points for a parallel circuit?
If one bulb breaks the bulbs in other branches stay on
The current splits up when it comes to a branch
If you add more bulbs they stay bright
High resistance?
Hard for electricity to flow
Small current
Low resistance
Easy for electricity to flow
Large current
