What is electricity

Renewable resource

A useful energy that is collected from renewable resources.

Friction

The force resisting the relative motion of solid surfaces sliding against each other.

Circuit

A path in which electrons from a voltage or current source flow.

Lightning

A naturally occurring electrostatic discharge during which two electrically charged regions temporarily equalize themselves.

Negative charge

A positive charge occurs when the number of electrons exceeds the number of protons.

Electro-Static

A branch of physics that studies electric charges at rest.

Watt

The watt is a unit of power

The electrical resistance of an object is a measure of its opposition to the flow of electric current

Voltage

An electromotive force or potential difference expressed in volts.

Neutron

A subatomic particle with almost an identical mass as a proton but without an electrical charge.

Insulator

An object or a material that does not allow the flow of an electrical current freely

Proton

A subatomic particle with a positive electrical charge.

Volt

The unit for potential difference, equivalent to one joule per coulomb.

Electricity

A form of energy that results from the interaction of charged particles, such as electrons or protons.

Parallel Circuit

A circuit in which there is more than one path along which electrons can flow.

Ohm

The unit for resistance, equivalent to one volt per ampere.

Repulsion

The electric or magnetic force by which one object pushes another one away from it.

Amperage

The strength of an electric current in amperes.

Electricity generation

The process of generating electric power from sources of primary energy.

Neutral charge

A neutral charge is the electrochemical occurrence where an atom has an equal number of electrons and protons.

Positive charge

A positive charge occurs when the number of protons exceeds the number of electrons.

Energy

The type of energy produced by a moving electrical charge.

Current

A stream of charged particles, moving through on electrical conductor or space.

Power

Power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.

Electron

A subatomic particle with a negative electrical charge.

Conductor

An object or type of material that allows the flow of charge in one or more directions.

Static

An electrical charge that tends to stay on the surface of an object, rather than flowing away quickly.

Battery

A connection of two or more cells.

Resistance

The property of a substance that hinders electric current and converts electrical energy to different forms of energy.

Ampere

The unit of electrical current, equivalent to one coulomb per second.

Series Circuit

A circuit in which there is only one path along which electrons can flow.
