What property determines the choice of material that is used for the inside of an electrical wire and the material that is used for the outside of the wire?

The most important property is the conductivity of the material under consideration. A high conductivity is needed for the inside, and a very low conductivity for the outside.
Only after this can we consider other factors, such as cost, strength, toxicity, flammability, flexibility, corrosion resistance and ease of making and shaping.

What type of material will you find outside of an electrical circuit to protect it?
I think that it is insulation but you might have to check elsewhere to make sure. :D
What structural property of a virion has in common with cellular organism?
A virion is the infectious form of a virus outside of the cell before it invades. Both cells and viruses have genetic material.
What is the difference betwwen physical property and chemical property?
Physical properties are the 'Measurable properties which describe the physical system's state', such as Density, Fusibility etc. Whilst 'Mechanical Properties' as it says in Collins CDT Design and Realisation book Pg 39, that a Mechanical property is a property which is the behaviour of the material when its linked to the application of force such as Strength.
What is more important for amperage rating wire size or insulation temperature rating?
Wire size determines how much current can be safely conducted. Insulation type and rating determines other factors, such as where the wire can be used and maximum voltage. It should be noted that the high voltage lines that are hanging from the really large electrical towers are among a class of wires that have NO insulation around the outside of the wire. They are instead, connected to the towers with large insulators that prevent electrical energy from being lost through the towers.
How can you tell if the extension cord is for indoor use only?
An indoor extension cord is usually made from the same material that your lamp cords are made from. An outside cord has an outer jacket that is usually round in shape and has the electrical data printed on the length of the cord.
What is capacitor transducer?
A: Some material have the property of a capacitor and this property can be varied by outside forces making it a transducer
What property determines whether an object is part of the solar system or outside the solar system?
If the object is gravitationally bound to the sun, it is part of the solar system. If not, not.

Extracellular material is found outside of the cell.
Who determines if they are a subcontractor?
The company who bided on the job is who determines if they are hiring outside their company. If they do this is generally called sub contracting.
What is the technique that uses the reflection of electromagnetic waves to determine the location or direction of outside objects?
RADAR determines the distance and direction to anything that reflectsradio waves ... usually material objects, but it responds to atmosphericphenomena too.
What mineral material is used as an insulator in electrical equipment?
Magnesium oxide is used in heating elements to isolate the inside heating wire from the elements outside sheath. This same material is used in Pyrotenax mineral insulated cables as an insulation medium.
What structural property of a virion has in common with cellular organism?
A virion is the infectious form of a virus outside of the cell before it invades. Both cells and viruses have genetic material.
What is Another name for electrician?
In England they call an electrician, "Sparky". In the US, if the electrician works on distribution system they are known as "linemen" or "outside electricians" (they work outside of personal property), the electricians that install the electrical system inside personal property are known as "inside wireman", "journeyman electrician", "journeyman wireman", or just "journeyman".
