These particles are gained or lost to cause an object to become charged.
What are electrons?
100
This will occur when two positively charged objects are placed near one another.
What is repelling?
100
Silicon is an example of this because it has electric charges that flow less freely than copper, but more freely than rubber.
What is a semiconductor?
100
If an object gains electrons it becomes this charge.
What is negative?
100
If an object loses an electron, this will happen when it approaches a positively-charged ion.
What is repel?
200
This is what happens to negative charges that are picked up by your socks when you rub your feet across the carpet and then later they are no longer there.
What is they are transferred to another object?
200
This is the region around the magnet that can be used to measure magnetic forces.
What is the magnetic field?
200
Two objects that are near each other but not touching can cause each other to become charged because of this.
What is induction?
200
Water is considered to be a conductor because water allows this to happen.
What is allows charges to flow through it?
200
In this type of current, electric charges switch direction around 60 times each second.
What is alternating current?
300
In this there are many different paths that electric current can follow.
What is a parallel circuit?
300
+---+-++-
-+--+-+---
Based upon the arrangement of the symbols above, you could expect this object to be this.
What is not magnetized?
300
The work or force needed to move an electric current between two points is called this.
What is electric voltage?
300
Objects powered by batteries run on this type of current.
What is direct current?
300
This describes an object that does not allow electric charges to flow freely. Rubber is an example.
What is an insulator?
400
During an electric storm, the bottom of a cloud gains a strong negative charge. If you were to observe the charge of a tall metal pole directly under this cloud, you would expect to observe it to have this charge.
What is a positive charge?
400
An object is determined to be magnetic based upon this.
What is the alignment or arrangement of the atoms or domains?
400
This is the part of the circuit that is being powered by electric current.
What is the load?
400
These are things that interact with particles in Earth's atmosphere to create the beautiful light display called the aurora.
What are particles from the sun?
400
If a wire has a low resistance, it is probably this.
What is short, thick, and cool?
500
When the distance between two oppositely charged objects decreases, the electrical force does this.
What is increases?
500
When the north and south poles of atoms in a material line up they form these.
What are domains?
500
This is the rate at which electric charges pass a given point.
What is electric current?
500
Wire thickness, wire length, and this can all affect the resistance of a wire.
What is wire temperature?
500
Rubbing the pole of an existing magnet in one direction onto an object causes this.
What is the alignment or arrangement of the object's domains?
