Do you really mean 'enhance', or do you simply mean 'allow'? If the latter, then presumably the answer you are looking for is 'conductor'! If you mean the former, then the answer is a 'good conductor'.
Conductors are any material that conducts the flow of electricity, which would include Copper. Insulators are any material that restricts the flow of electricity which would include plastic.
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Good conductors are metals, such as copper or aluminum. Materials that allow the flow of electrons, but not as freely as good conductors are known as semiconductors. These are primarily silicon or germanium, that is "doped" with specific types of impurities to allow their current to be better controlled by the application of a voltage. Heat will also increase the flow of electrons in a semiconductor.
Electricity does flow back to the power plant. This electricity is what forms the circuit needed to actually deliver the electricity to you when you need it.
Electrons don't have electricity they only posses energy, Electricity is defined as the flow of electrons! In conductors the flow of valence electrons are called Electricity! therefore inducing a current in it! generally the direction of flow the current is the opposite of the direction of flow of electrons(D.C)!

Conductors are any material that conducts the flow of electricity, which would include Copper. Insulators are any material that restricts the flow of electricity which would include plastic.
A conductor allows electricity to flow. An insulator does not.

Depends on the material. The electricity can flow through metal better then it can through wood because wood is a conductor of electricity (example).
A "resistance" or "resistor".
a electrical conductor is a material that electricity can flow through.
An insulator is a material that slows the flow of heat and electricity. Electrical wires need insulators periodically along it's length over whatever distance.
Electricity can pass through a wide verity of material that are conductive.
it is called conductivity.
