Electric Charge
These are small particles made up of protons, neutrons, and electrons.
What are atoms?
Unlike gravity, electrically charged objects can be either attractive or this.
What is repulsive?
Every proton and electron is surrounded by this that exerts a force on other electric charges.
What is electric field?
The imbalance of electric charge on an object is considered this.
What is static charge?
The SI unit for electric current is this.
What is the Ampere?
This part of an atom has no electric charge.
What are neutrons?
If two objects are negatively charged, the objects will do this.
What is repel each other?
When an electric charge is transferred between objects in contact, it is called this.
What is charging by contact?
When you feel an electric shock as static charge moves from your hand to a doorknob, it is considered this.
What is electric discharge?
A battery, lightbulb, and connecting wires for a simple form of this.
What is an electric circuit?
This is the part of an atom with a negative charge.
What are electrons?
If one object is positively charged, and the other is negatively charged, the objects will do this.
What is attract each other?
The rearrangement of electric charge due to the presence of an electric field is called this.
What is charging by induction?
In nature, a spectacular example of electric discharge is this.
What is lightning?
The type of circuit that provides more than one closed path for current to follow is this.
What is a parallel circuit?
An atom that has equal numbers of protons and electrons, has equal positive and negative charges, and is considered this.
What is electrically neutral?
The electric force between two charges does this as the distance between the object increases.
What is decreases?
Plastics, glass, rubber and wood, are examples of materials in which electric charges do not move easily, and are called this.
What are insulators?
One way to protect a building from the damaging effects of lightning is by installing this to the top of the building.
What is a lightning rod?
The measure of how difficult it is for electrons to flow in an object is measured in Ohms, and is called this.
What is electric resistance?
If an atom gains or loses electrons, it is considered this.
What is electrically charged?
As the amount of charge on either object increases, the electric force between the objects does this.
What is increases?
Materials, including metals such as gold or copper, in which electric charges can move easily are considered this.
What are conductors?
The process of providing a direct path to drain excess charge into Earth is called this.
What is grounding?
This is the measure of electrical energy transferred from one point to another in a circuit.
What is voltage?
