1

Electricity

A form of energy and a good way to transport electricity from one place to another. Caused by moving charged particles (flow of electrons).

2

Conductor

Are materials that allow the flow of charge to flow through them

New cards
3

Insulators

Are materials that do not allow the flow of charge to flow through them

New cards
4

Static electricity

A stationary electric charge, caused by produced most commonly by fiction.

New cards
5

Current Electricity

A flow of charged particles

New cards
6

Electric Circuits

A path for electric charge to flow along

New cards
7

Current

A measure of the flow of electrons at a point in a circuit

New cards
8

Law of Conservation of Charge

Electric charge can not be created or destroyed, the amount of charge remains the same. When an object changes its charge it doesn’t destroy it but transfers it.

New cards
9

Voltage

Is a measure of the difference in electrical potential energy between two points in a circuit.

New cards
10

Circuit Breakers

A safety device that interrupts the flow of current to a circuit

New cards
11

Switch

A switch that turns off contact of the wires is broken so no more current can flow through

New cards
12

Magnetism

Is the force exerted by magnets when they attract or repel each other.

New cards
13

Magnetic field

The area around a magnet in which the effect of magnetism is felt.

New cards
14

Magnet

A material that produces magnetic field

New cards
15

Electromagnets

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
