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
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.
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.
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.
Metallic conductors contain metal in them. They are used to help magnetize certain items. Non metallic are safer as they do not contain metals.
A conductor will conduct something such as electricity, heat, sound. Basically some form of energy. A non-conductor simply won't.
A conductor can conduct electricity; a nonconductor act as an isolator.
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)
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
The NM represents the type of sheath on the cable. NM stands for Non Metallic sheath cable..
ACT has thermoplastic insulated wires. AC is old MC is the modern cable.
Cable sheath current is a current induced in the sheath by radio, magnetic or other interference, or a fault condition. The cable sheath should be grounded at one end so that this current flows to ground safely.
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
The metallic sheath prevents the ingress of moisture, while the armour protects the cable from damage from foreign objects.
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.
Electrical Sheathing is various forms of metallic or non-metallic covering over conductors. Nonmetallic-Sheathed Cable is what is known by the brand name Romex.
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
NEC, Article 336 covers the use, installation and construction specifications for nonmetallic-sheathed cable. Nonmetallic-sheathed cable may be used for either exposed or concealed wiring.
Difference between coaxial cable and STP cable used for computer networking?
THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
Yes
The colours will be, black, white and a bare copper ground.
The difference between Armored cable and Metal Clad cable is that the MC cable has a EGC (Equipment Grounding Conductor). Both cables are armored, and look almost identical so watch out.
The difference between a cross cable and a state cable is that a cross cable, or crossover cable, is used specifically to connect two of the same devices.
No. it is plastic.
