Molecules
A material that allows heat or electricity to pass through it is called a conductor. The opposite of that is called an insulator. For electricity, the wire inside is the conductor, while the plastic on the outside is an insulator.
A material that electricity can conduct electricity.
An insulator.
An electrical "insulator".
Electricity is the flow of electrons across a conductor. A conductor can be many things, copper is one of the most efficient. Voltage is what moves the electrons. It works like the pressure that pushes water through a hose.
Electricity, as used by us in such things as our computers and TVs etc, requires a conductor. It is the movement of electrons along that conductor which most people call electricity. This cannot travel through space. However electricity is also a part of and related to the electromagnetic spectrum which can travel through space.

a conductor
Electron flow; also known as electrical current.
An electrical conductor is a material that can carry electricity.
A substance that conducts electricity is a conductor. There is no special name for one that is solid; if you need to specify that it is solid, just call it a "solid conductor".
An insulator.
electricity
an open circuit
conductor
Electrons bumping into each other transferring energy called electricity.
A material that electricity can conduct electricity.
