Atoms
What is the simplest form of matter?
This repels a positive charge.
What is a positive charge?
The buildup of charge on an object.
What is static electricity?
The flow of electric charges through a material.
What is electric current?
Charges move easily through this type of material.
What is a conductor.
A negatively charged subatomic particle.
What are electrons?
This attracts a negative charge.
What is a positive charge?
The transfer of charges from one object to another by direct contact.
What is conduction?
The unit for the rate of electric current flow.
What is an Ampere (or Amp).
Charges do not flow through this material.
What are insulators?
Ion
What is an atom with unequal numbers of protons and electrons?
The interaction between electric charges.
What is electricity?
How electric charges flow.
What flows from negative to positive charge?
This is needed to maintain a flow of current.
What is a closed electric circuit?
This type of circuit has only one path for charges to take.
What is a series circuit?
This is an example of a metallic element used in electric motors and house wiring.
What is copper?
They get weaker farther away from the electric charge.
What is an electric (electromagnetic) force?
The overall charge in an object stays the same, but moves to make positively- and negatively-charged areas.
What is polarization.
This flow of electrons is caused by a magnetic field, not by the transfer of charges.
What is induction?
The three parts of an electric circuit.
What are a device, source of electrical energy, and conducting wires.
The transition metal elements.
What type of element makes up most of the periodic table?
A force field that affects charged objects.
What are electromagnetic fields?
It is lightning.
What is natural discharge of static electricity?
This is a description of Ohms Law.
What is the relationship between resistance, voltage, and current? (V=Amps * Resistance, or Resistance = Volts / Amps)
(V=IR)
This is called voltage.
What is the difference in electric potential per charge between two points in a circuit.
