100
What happens to the thin metal strip in a fuse when too much electrical current flows through it?
The metal strip will melt.
100
What happens when two of the same charged objects move towards each other?
The objects repeal from each other

200
How many conductors does a series circuit have?
One
200
Name two possible ways that no light bulbs in a parallel circuit light up?
No energy source The switch is open The wires are not connected
200
How do you pull a cord out of an outlet?
By the plug
200
The build up of charges is called ______.
Static electricity
300

300
What happens if one of three light bulbs is removed from a series circuit?
All of the remaining light bulbs go out
300
What happens if one of two light bulbs is broken?
The other light bulb remains on
300
Why is it important for wires to be insulated?
You won't get shocked. It prevents short circuits.
300
Why does your hair move towards a balloon after you rub the balloon on your head?
The unlike charges attract (the balloon and your hair)

What is the resistor in a light bulb called?
The filament
500
A property of an object that does not allow electric current to flow easily through it is called ________.
Resistance or resistor.
500
What is the path the electrical current takes in a series circuit?
Flows from the energy source -----> switch/conductor ----> resistor -----> energy source.
500
Describe a parallel circuit.
Has two or more pathways. If one resistor is broken, electrical current will flow through the other resistor.
