A conductor - usually copper wire.
a copper wire
A metal conductor, such as copper wire, is commonly used to allow electricity to flow between a battery and a light bulb. Metal conductors have a high number of free electrons that can carry electric current easily.
A metal wire is typically used to allow electricity to flow between the battery and the light bulb. Metals are good conductors of electricity due to their free-flowing electrons that can carry electric charges. The wire completes the circuit, allowing the electric current to travel from the battery to the light bulb, providing power for it to illuminate.
I guess you mean, between a battery and something else.The generic name for materials which allow an electric current to flow through is "conductor". Specific examples include any metal, graphite, ions in a water solution.
The term that describes a material that does not allow light to be transmitted is opaque. Opaque materials absorb or reflect light, preventing it from passing through them.
Opaque materials do not allow light to pass through them.
Rubber
It's a light source.
Opaque materials have a dense molecular structure that absorbs and scatters light. This prevents light from passing through them, as it does not allow the light to travel through the material. This results in the material appearing solid and not allowing any visible light transmission.
An opaque material does not allow light to pass through it. These materials typically reflect or absorb light, preventing it from transmitting through the substance. Examples include metals, wood, and thick plastics.
