How are wires insulated?
In order to prevent fire as well as electrocution, insulation is used around electrical wiring to prevent sparks or electrical charges that could hurt people or their property. There are many types of wiring insulation, rubber being one of the most effective. Ceramic is another inert material that possesses strong insulating properties. Both of these materials have their drawbacks, however. One is expense. During the Second World War, after the Japanese Empire invaded and occupied the rubber-producing regions of Southeast Asia, rubber became an expensive commodity.
When an electric charge moves through a conductor there is an electric in the conductor?
current
How cavity wall insulation helps to reduce heat loss?
A major part of the heat transfer through a cavity wall lacking insulation is convection - and to a lesser degree radiation. When insulation is placed in the cavity between the walls it significantly reduces both convection (air doesn't move well through insulation like it does in empty space) and radition (the walls can't "see" each other through the insulation). For the insulation to be effective, the thermal conductivity of the material must be low enough that conduction through the insulation is much less than was present with convection.
Is the the human tissue a conductor or conduction?
It is a conductor. Conduction is the process which occurs when electricity flows through a conductor.
How many amps will 2Awg wire carry?
CEC - #2 copper, RW90 insulation, 120 amps. #2 aluminium, RW90 insulation, 95 amps. he is not talking about Amplifiers. he is talking about amperes, the unit of measure that indicates how much electricity can flow through a wire. and it depends on the length of the wire, but 2 gauge wire will handle about 208 amps. depends on how big the amps are
Can water be an electrical conductor using direct current?
Water can conduct current, but not as efficiently as a copper wire. There are some applications where a small current is used to sense the level of water through a conductor in an insulated container.
What is the purpose of insulator in overhead transmission line?
Overhead lines are uninsulated, as they depend upon the air to provide insulation. However, they must still be insulated from the towers or poles from which they are suspended. This insulation is provided using glass or ceramic insulators. The greater the line voltage, the longer the ceramic insulator, or the greater the number of glass insulator 'dishes'.
Why is insulation used in walls of buildings?
To keep heat in - and cold out. Many buildings are poorly insulated ( the 'standard' house-brick is the main culprit. This lets heat escape through the walls (and roofs) of buildings. Insulation traps the heat inside.
Can you get an electrical shock if you touch a wire covered in plastic?
No, the covering on the wire is insulation. This insulation is used to isolate the wire from any grounding medium, this includes a person. It is not a good idea to go around touching wires as there may be a nick in the insulation. If the nick goes all the way through to the conductor, and you touch that specific spot and you are grounded you will get a shock as you become part of the conductor.
What is the physics behind loft insulation?
Insulation impedes the flow of energy. In the case of insulating a loft, this energy is in the form of heat. In the winter, when the inside of the house is warm and outside is cold, the insulation makes it more difficult for heat to escape through the roof. In the summer, the insulation keeps the heat outside the house. The rate of that increased difficulty is called an R-factor, such as R-30 or R-60. The higher the R-factor, the better insulated a house will be. Up to 25% of heat loss in a house occurs through the roof, so in theory, a well insulated loft could reduce heating and cooling bills by 20-25%.
Describe the role of the myelin sheath?
Myelin sheath is the insulation of the CNS (central nervous system). Its helps electrical signals move along nerves. Basically, its synonymous with insulated wire. Again the insulation help the signal move in a smooth and controlled fashion through out the body.

Can you bury insulated outdoor wire run through PVC?
you could but the pipe might fill with rain water during a storm, but as long as it doesn't have any opening/cuts in the wire insulation it should be fine.
Can the electric field generated by the conducting wire penetrates the PVC insulation covering it?
It's actually a magnetic field, not an electric field, but the answer is 'Yes'. Pass some DC ... like from a battery that's operating a flashlight bulb ... through an insulated wire, and lay the wire over a compass. You'll plainly see that somethingthat affects the compass got through the insulation.
How does loft insulation work?
Generally, the heat in your house rises. This can mean that a lot of heat is lost through the roof. If you put insulation in your loft, the insulation is a poor conductor of heat so the heat stays below the loft and your loft is cold. Then less heat gets to the roof and so less heat is lost.
What does electric current will flow through the earth wire mean?
Insulation failure in an electrical equipment will cause some amount of current, depending upon the severity of fault flows through the metallic body and then through the earth wire which is connected to the body.
Does insulation rated R35 allow more or less heat to pass through it than insulation rated R1?
R35 insulation allows LESS heat to pass through than R1 insulation.
