Physical Sciences

a device used to measure electrical current.

standard unit of electric current

A component that stores chemical energy to be used as a power source

A pathway for electricity to flow around

A representation of an electrical pathway

A complete pathway that allows electrical current to flow

Part of an electrical circuit e.g. battery

As one amount increases, another amount increases at the same rate

The flow of electrons through a circuit

A very small subatomic particle with negative charge

As one amount increases, another amount decreases at the same rate

A component that produces light

A device that can measure both resistance and voltage

The part of a battery that electrons flow out from

The standard unit of electrical resistance

The relationship between current, voltage and resistance

A broken pathway that does not allow electrical current to flow

The part of a battery that electrons flow towards

A material's opposition to the flow of electrical current

A component designed to lower the current passing through a circuit

A component used to open or close a circuit

Part of a component where electrical current can leave or enter

The standard unit of voltage

The amount of energy per charge

A device used to measure voltage

component made of a flexible strand of conductive metal

The range of light frequencies that we can see

Allowing nearly all light to pass through

The passing of light through a material

Allowing only some light to pass through

The bending of light as it passes into a new material

The bending of light as it bounces off a surface

A transparent object with flat surfaces, which refract light

Movement that is repeated at regular intervals

The time it takes a wave to go through its full motion once

Not allowing light to pass through
