Principles of Electricity
What is the Definition of an Electric Field?
The space around a charged object where it can push or pull other charges.
What is a Magnetic Field?
The area around a magnet where it can attract or repel other magnets.
What is a Resistor?
A component that slows down an electrical current.
What is Ampere (Amp)?
The unit for measuring electric currents.
Variable: A
What is a Parallel Circuit
A circuit that is connected to where there is multiple paths for the current to flow.
What is a Direct Current?
An electric current that flows in one direction.
What is a Magnetic Domain?
A region in where the magnetic fields of atoms are grouped or aligned in the same direction.
What is a Conductor?
A material or substance that allows electric currents to flow easier through.
What is Ohm?
The unit of measuring resistance.
Variable: Ω
What is a Series Circuit?
A circuit that is connected in a single path.
What is an Alternating Current?
An electric current that changes direction back and forth.
What are Magnetic Poles?
The ends of a magnet where the magnetic force is the strongest.
What is an Insulator?
A material or substance that does NOT allow electric currents to flow easily through.
What is Volt?
The unit for measuring voltage.
Variable: V
What are Transformers? (not the robots that turn into cars)
Devices that change the voltage of an electric current.
What is Potential Difference?
The difference in electric potential energy between two points.
What is an Electromagnet?
A magnet created by electricity.
What is a Generator?
A device that turns mechanical energy into electrical energy; The opposite of a Motor.
What is Power?
The rate electrical energy is used or produced.
Variable: P
What is Voltage?
The measure of potential difference. (The amount of force that pushes energy (potential difference))
What is Electromagnetic Induction?
An electric current mad by changing (moving) a magnetic field.
What is a Motor?
A device that turns electrical energy into mechanical energy; The opposite of a generator.
What is Equivalent Resistance?
The total resistance in a circuit.
Variable: R
