So that the living organisms and other wires/metals are not affected by the current in a given wire. In the absence of insulation two wires coming in contact may cause short circuit and also there is a risk of death of the living organisms coming in contact. There is one more reason that insulation minimizes charge leakage from the wire.

What is the action of removing the insulation from wire?
The action of removing insulation for a wire is called stripping.
What would happen if electric cords did not have plastic around them?
The plastic is a form of insulation. Insulation used to be made from non-plastic materials like cloth. It protects the wire from the outside world. Without insulation the electricity would cause shocks, fires, and short circuits.
Can all wire be reconnected using different wire?
Yes, as long as the different wire is of the same size or larger and has the same insulation factor as the original wire.
What is the insulation factor for a number 6 wire?
The main insulation factors of the wiring used in every day use are 60, 75 and 90 degrees C. A #6 wire can be any of the above. The higher the insulation factor, the higher the ampacity of the wire becomes. For a #6 wire the amperage is 60 C - 55 amps, 75 C - 65 amps and 90 degrees C - 65 amps.
What is the maximum current recommended for 30 gauge copper wire?
Sorry, there is no such wire size as "30 gauge" in the AWG (American Wire Gauge) system. For the ampacity rating of all standard conductor sizes, go to Table 310-16 of the National Electric Code. If you mean what wire size will carry 30 amps then a #10 copper wire insulation rating of 90 degree C is rated at 30 amps.
What is a frayed wire?
Commonly, an electric wire which has insulation that is worn, torn, cut or damaged in some way.
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.
What is a different between the insoluted wire and other wire?
It is not 'insoluted wire'. That one in named as ' insulated wire' Usually metallic wire carries the current. Just to avoid electric shock it is to be covered by insulators such as rubber or plastic. Some times we use nickel coating which also serves the purpose of insulation.
What is the purpose of a live wire?
it gives you an electric shock
Why does a hairdryer not need a cable with an earth wire?
Hairdryers often have a double-insulated design, which means they have an extra layer of insulation to protect against electric shocks. This eliminates the need for an earth wire in the cable because the double insulation provides adequate protection against electric leakage.
What is the role of the myelin in a neuron?
A neuron is analogous to an electric wire. If you look at an electric wire going from a lamp to a wall plug, you do not see the actual wire. Instead, you see the insulation. If you would scrape off the insulation, you would see two wires. If those two wires touched you would hear a loud pop. Then a circuit breaker would throw. The wire would be just as good as it was before you removed the insulation. The wire carried the electricity. The insulation protected the wire and let it do its job. Without the insulation, the bulb would not work. The Myelin sheath protects the nerve from outside forces. It lets it carry its signal free from outside influence. It is a piece of insulation.
The term magnetic wire indicates a wire that has what for insulation?
Magnetic wire has a coating of varnish for an insulation.
What is the action of removing the insulation from wire?
The action of removing insulation for a wire is called stripping.
How to use wire strippers effectively for stripping insulation from wires?
To use wire strippers effectively for stripping insulation from wires, first select the appropriate size notch on the wire stripper that matches the gauge of the wire. Place the wire in the notch and squeeze the handles together to cut through the insulation. Gently pull the wire stripper away from the wire to remove the insulation. Be careful not to cut into the wire itself while stripping the insulation.
What is the purpose of using three different colored wires in an electric iron?
The purpose of using three different colored wires in an electric iron is to distinguish between the live wire (typically red), neutral wire (typically black or blue), and the earth wire (typically green or yellow). This helps ensure that the electric iron is wired correctly and safely.
What is the proper technique that wire strippers use to remove the insulation from electrical wires?
To remove insulation from electrical wires using wire strippers, place the wire in the appropriate gauge slot, squeeze the handles to cut through the insulation, and then pull the insulation off the wire. Be careful not to cut into the wire itself.
What is a sentence using the word insulation?
An electric lamp may be dangerous to use if its wire has lost its insulation. Attics are lined with insulation to help maintain a comfortable temperature in the house. The colonial powers ended Japan's self-imposed insulation from the Western world.
