Lesson 1
The force between two objects
What is electric force?
The continuous flow of electric charges through a material
What is an electric current?
The law that states that resistance in a circuit is equal to voltage divided by current
What is Ohm's law?
A connection that allows current to take the path of least resistance
What is a short circuit?
A method of charging an object by allowing electrons to flow from one object to another object through direct contact
What is conduction?
A region around a charged object where the object's electric force is exerted
What is an electric field?
A complete, unbroken path through which electric charges can flow
What is an electric circuit?
An electrical circuit in which all parts are connected one after another along one path
What is a series circuit?
The round prong of a plug that connects any metal pieces in an appliance to the safety grounding wire of a building
What is the third prong?
A method of redistributing the charge on an object by means of the electric field of another object; the objects have no direct contact
What is induction?
The build up of charges on an object
What is static electricity?
A material that allows electric charges to flow.
What is a conductor?
An electric circuit in which different parts of the circuit are on separate branches
What is a parallel circuit?
Allowing charges to flow directly from the circuit into the building's ground wire and then into Earth in the event of a short circuit
What is grounded?
The process through which electrons are attracted to or repelled by an external electric field, causing the electrons to move within their own atoms
What is polarization?
The law that states that charges are neither created or destroyed
What is the conservation of charge?
A material that does not easily allow electric charges to flow
What is an insulator?
Power = Voltage x Current
What is Power Equation?
A safety device with a thin metal strip that will melt if too much current passes through a circuit
What are fuses?
The loss of static electricity as electric charges transfer from one object to another
What is static discharge?
The transfer of electrons from one uncharged object to another uncharged object by rubbing
What is friction?
The difference in electrical potential energy per charge between two places in a circuit
What is voltage?
A scientist who set up a circuit with a voltage between two points on a conductor
Who is George Ohm?
A reusable safety switch that breaks the circuit when the current becomes to high
What is circuit breaker?
The measurement of how difficult it is for charges to flow through an object
What is resistance?
