Blow up the balloon and comb your hair
Tie the balloon to the hair
Rub the balloon against your hair
Wear the balloon as a hair tie
It will short circuit
You will get a shock
The battery will turn blue
The battery will disappear
Electricity stops flowing from the switch and therefore the circuit is broken, providing no electricity to the object being powered
Electricity is able to flow through the circuit powering an electrical device
Electricity is not able to flow through the circuit but it can still power an electrical device
Electricity is able to flow through the circuit but it cannot power an electrical device
They will attract.
They will repel.
They will attack.
They will do nothing.
Something that electricity can't move through
Something that makes electricity stop
Something that electricity can move through
Something that makes electricity repel magnets
Because metal is cheap
Because metal is a good conductor
So they can bend easily
To keep the wire warm
So it looks nice
To conduct electricity
To insulate the wire from other things
The bulb will turn off
There will be no change to the bulb
The bulb will get brighter
The bulb will get dimmer

W = Fd

PE = mgh
The ph, the voltage, and its frequency
What the material is, the flammability, and the current

What the material is, the length, and the thickness
Alex and the door knob were both postively charged. When Alex touched the door knob, he felt a shock because like charges attract.
The doorknob was too close to the doorbell, and a wire must have been touching it. Alex has no charge because he is a person.
Alex acquired charge by walking across the carpet, probably stripping electrons off the carpet. These charges jumped to the doorknob which probably had the opposite charge of Alex. The shock was the current of these moving charges from Alex to the doorknob.
Alex and the door knob are both insulators. It is impossible for Alex to feel a shock.
A short circuit
It connects the electrical appliance to the ground so a short circuit won't fry it
It carries electricity
It is an artificially intelligent "smart" prong used to determine if a machine is on or off
