Why tungsten metal wire is not used in heater?
A heater does not get hot enough to benefit from the expense of using tungsten wire. Most heaters use either wire made of an alloy called nichrome or plated ceramic heating elements. Heaters generally operate at red or orange heat (i.e. 1409F to 1908F) and can use nichrome wire. Lightbulbs operate at white heat (i.e. greater than 2309F) and use tungsten wire, but tungsten is hard and expensive to make into wire compared to softer metals.
What is the correct wire gauge of ordinary household wiring?
Mainly copper is used for household wiring but it may vary.
When wiring a house do you have to use the black wire as the hot wire?
No, there are different occasions when the red of a three wire cable gets used as a hot wire. There also times when the white wire gets used as a hot but has to be re identified as a hot with marking tape. When wiring baseboard heaters the cable used is red and black with no white wire in the set.
What is the meaning of breakdown in insulation in domestic wiring?
The outer plastic case on wire has got 2hot and gone all black hard an brittel
A metal used in wire?
The answer is copper.No, the answer is not always copper, it will depend on the purposes for which the wires are to be used!Yes, copper is used a lot for electrical wiring but other metals are also used, such as tungsten for incandescent light bulb filaments.Some other examples are: galvanised iron or steel wire is used for fences around gardens, etc. and if wires are used to make jewelry, they are often made of silver, gold or platinum.Another answerDepends on the purpose:for electric household wiring copper is used.for ultra high speed capacity internet communication wiring: glass fibre Comment: Glass fiber is not made of metal, it is made of glass!
What is tungsten wire what is it made up of?
tungsten is a wire used in making filaments of the bulb.
Why are conducters used in domestic wiring insulated?
Wires are insulated to stop a short circuiting between the common neutral wire and the wire that supplies the potential voltage to the load of the circuit.
Why tungsten wire is not used in an electric heater?
Too expensive. Ni-chrome wire is cheaper.
Is copper wire the same as thugsten wire?
No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
Why do you not use gold wire in domestic wiring?
Because it is simply too expensive and there is not enough gold.
What is the blue and white wire for?
Supplying power. Different manufacturers and different vehicles using different wiring systems. There is generally not a standard as there is in domestic power wiring.

A multipurpose wiring tool can be used to?
Wire and Crimp.
Why is Tungsten used in lightbulbs?
Tungsten is used in bulbs as filament, because it is the only wire that can be bent easily to produce friction. In the 5mm coil of the wire there are almost 15 rounds of coiling and when the electrons flow through it, it glows and emits heat as well due to friction.
What is the correct wire gauge of ordinary household wiring?
Mainly copper is used for household wiring but it may vary.
What is the use of wire terminal?
A wire terminal is used in electrical wiring. It is used to hold the wires when wiring switches and receptacles. There are different types of terminals including screw terminals.
How are batteries connected in a flashlight?
The electrons from the battery go through the wiring to the bulb. Inside the bulb, they heat a tungsten wire so hot that it glows, giving off light.
