100
The tiny building blocks of everything. They're tiny and they're teeny!
What are atoms?
100
Particles moving between atoms in storm clouds become this.
What is charged?
100
This subatomic particle flows through the wire when an electric field is present.
What is an electron
100
What is the thing that closes and opens the current in a circuit.
What is a switch.
100
Every magnet has two of these
What is a magnet
200
The same number of positive particles as negative particles.
What is neutral?
200
North and south poles do this
What is attract
200
this is a path in which electric charges can flow.
What is an circuit.
200
This is the SI unit of electric current.
What is V or voltage
200
Electric Current move easily in these.
What are conductors
300
When the positive and negative charges no longer balance. This is when negative charges are built up much more than positive.
What is static electricity?
300
This is the reason magnets might repel each other.
What is like poles.
300
Name things (2) that electrons flow easily through. Examples
What is wire, metal poles, anything metal.
300
What factors affect the strength of electric forces?
resistance, amount of electricity, # of bulbs.....
300
Transfer of electrons between objects in contact
What is charging by contact
400
An electric charge in motion. (electrons in motion usually in a wire)
What is an electric current?
400
These factors affect the strength of magnetic forces.
What are strength, size, distance....
400
Name at least 2 things that could slow the flow of electrons in a circuit.
wood plastic rubber
400
In this circuit, devices are connected so there is only 1 closed path for current to follow.
What is series
400
A current carrying wire wrapped around an iron core is called this.
What is electromagnet.
500
Electric currents are surrounded by these....
What is an electric fields
500
Only materials containing these elements are magnetic
What is iron, cobalt, nickel, and a few other rare earth elements
500
This subatomic particle flows easily in a circuit.
What is electron
500
This is a circuit where there is more than one close path for a current to follow.
What is parallel
500
This is a measure of the amount of electrical energy transferred by an electric charge as it moves from one point to another in a circuit.
What is voltage
