What is the difference between metallic and non-metallic cable?

Answer 1

There is a big difference between Non-metallic minerals and metallic minerals.Metallic minerals are composed primarily of metallic elements and have a metallic lustre and other properties, such as the ability to conduct electricity. Non-metallic minerals do not have these characteristics

Answer 2

This question can apply to either electricity (electron flow) or heat (thermal energy transfer).

Let us start with electricity:

An insulator exposed to a voltage will not let electrons flow (will not let current flow) until a very high voltage is applied, at which point the insulator breaks down (changes composition) and allows a current arc.

A conductor exposed to a voltage will allow electrons to flow and the current flow will be roughly proportional to the applied voltage.

Now, let us go to heat:

An insulator resists the transfer of molecular vibration energy, but what energy is transferred is roughly proportional to the temperature differential.

A conductor allows the transfer of molecular vibration energy and the transfer is roughly proportional to the temperature differential.

Answer 3

Metallic elements usually conduct electricity as compared to non metallic elements.

Metallic elements are usually good conductors of heat whereas non metallic elements are bad conductors of heat.

Metallic elements have high boiling and melting points(except Mercury) while non metals have low high boiling and melting points(except graphite and diamond)

Metals are ductile i.e can be drawn into wires whereas non metals are not ductile.

Metals are sonorous, usually shiny,have smooth surfaces while non metallic elements are dull in colour and not sonorous.

Metallic elements are malleable whereas non metallic elements are not.

Answer 4

The difference between a conductor and non conductor is that:

Conductor: that particular solution which can conduct electricity is known as a conductor but does not chemically change it self ; it is a criteria flow of ions for e.g. HCl, H2SO4.

Non-Conductor: substance which does not allow the passage of electricity and they are also called insulators For e.g. organic solution, plastic, glass.

Answer 5

Metallic conductors contain metal in them. They are used to help magnetize certain items. Non metallic are safer as they do not contain metals.

Answer 6

A conductor will conduct something such as electricity, heat, sound. Basically some form of energy. A non-conductor simply won't.

Answer 7

A conductor can conduct electricity; a nonconductor act as an isolator.

Answer 8

Metallic elements usually conduct electricity as compared to non

metallic elements.

Metallic elements are usually good conductors of heat whereas

non metallic elements are bad conductors of heat.

Metallic elements have high boiling and melting points(except

mercury) while non metals have low high boiling and melting

points(except graphite and diamond)
