Electricity

Science

A material that lets electricity pass through easily

Conductor

A material that lets electricity pass through easily. Conductor. A conductor is a material that allows electricity to flow through it with little resistance.

A measure of the net positive or negative particles in an object

Electric charge

A measure of the net positive or negative particles in an object. Electric charge. Electric charge is a property of particles that causes them to attract or repel each other based on their positive or negative nature.

A closed loop through which electric current can flow

Electric circuit

A closed loop through which electric current can flow. Electric circuit. An electric circuit is a path that allows electricity to travel from one point to another.

A flow of electric charge, it is measured in amperes (A)

Electric current

A flow of electric charge, it is measured in amperes A. Electric current. Electric current is the movement of electrons through a conductor, like a wire.

A device that turns electrical energy into movement, or mechanical energy

Electric motor

A device that turns electrical energy into movement, or mechanical energy, is an electric motor. An electric motor converts electricity into motion to power machines and equipment.

The ability of a material to slow or stop the flow of electric current

Electric resistance

The ability of a material to slow or stop the flow of electric current. Electric resistance. Electric resistance is how much a material opposes the flow of electricity through it.

A temporary magnet made of wire coiled around an iron core

Electromagnet

A temporary magnet made of wire coiled around an iron core. Electromagnet. An electromagnet is a magnet created by electricity that can be turned on and off.

A device that uses a magnet to turn mechanical energy into electrical energy

Generator

A device that uses a magnet to turn mechanical energy into electrical energy. A generator converts movement into electricity using magnets and wires.

A material that does not let electricity pass through easily

Insulator

A material that does not let electricity pass through easily insulator. An insulator is a substance that stops electricity or heat from moving through it.

An object that attracts iron and some other metals

Magnet

An object that attracts iron and some other metals. Magnet. A magnet is a material that produces an invisible force, called a magnetic field, which attracts certain metals.

The area around a magnet where its magnetic force acts

Magnetic field

The area around a magnet where its magnetic force acts. Magnetic field. It's the invisible space around a magnet where magnetic forces can influence other objects.

The part of a magnet where the magnetic force is strongest

Magnetic pole

The part of a magnet where the magnetic force is strongest. Magnetic pole. A magnetic pole is where the magnetic force of a magnet is concentrated and strongest, usually at its ends.

A circuit in which current can flow through more than one path

Parallel circuit

A circuit in which current can flow through more than one path. Parallel circuit. A parallel circuit is a type of electrical circuit where components are connected in separate branches, allowing electricity to flow through multiple paths.

A circuit in which there is a single path for current to follow

Series circuit

A circuit in which there is a single path for current to follow. Series circuit. A series circuit connects components one after another, so the same current flows through each component.

The electric charge that builds up on an object

Static electricity

The electric charge that builds up on an object. Static electricity. It's the imbalance of electric charges within or on the surface of a material.
