science 9 term 1 electricity

A form of energy related to electric charges. It originates directly from these electric charges.

Electricity

These can be either positive or negative.

Electric charges

A tiny particle with a negative charge.

Electron

A tiny particle with a positive charge.

Proton

Charges that are identical (such as two negative charges or two positive charges) repel or push away from each other.

Like charges

Charges that are opposite (a positive and a negative charge) attract or pull toward each other.

Unlike charges

This type of electricity occurs when electric charges stay in one place instead of moving.

Static electricity

This type of electricity occurs when electric charges move or flow along a path.

Current electricity

These are materials that allow electricity to flow through them easily.

Conductors

Materials that do not allow electricity to flow through them easily

Insulators

An injury that occurs when an electric current passes directly through the body

Electric shock

A device that consumes electrical power in order to perform work

Appliance

The socket or receptacle where an electrical plug is inserted to draw power

Outlet

A component that produces light by using electricity

Bulb

A simple drawing that visually demonstrates how various electrical parts are interconnected

Diagram

A simplified sign or drawing used in schematics to represent a specific circuit part

Symbol

It is a closed path through which an electric current can flow. It is constructed from different parts that operate and work together as a unit

Simple electrical unit

When a circuit path is entirely complete and unbroken, electricity flows seamlessly throughout it

Complete circuit

This continuous flow of electricity is what powers devices to perform their functions, such as lighting up a bulb

Powering devices

It provides the path where electric current flows from one component to another.

Electrical wire

It opens or closes the circuit to turn the flow of electricity on or off.

Switch

It gives electrical energy that pushes current through the circuit.

Battery

It supplies alternating current, where the flow of electricity changes direction.

It is a load that uses electrical energy to produce light.

Light bulb

It controls or limits the flow of electric current in the circuit.

Resistor
