What amperage is 14 2 wire rated at?
Even assuming you mean 14 swg (or awg) wire, the safe working current, and the fuzing current would have different values. And assuming further that it is copper wire to which you refer.
72 in piece of wire that you will cut into pieces and form the frame of a cube What is the volume of the cube that you can make with this wire?
6 in x 6 in x 6 in = 216 cubic inches
A copper wire is to have a length of 16 cm with a tolerence of 0.02 cm how much must be trimmed from a wire that is 18 cm long for it to meet the specifications?
at least 1.98 cm and no more than 2.02 cm
Suppose that 13 inches of wire costs 39 cents. At the same rate how many inches of wire can be bought for 24 cents?
Each inch of wire cost 3 cents and so 24/3 = 8 inches of wire
Joel has a 50 meter roll of copper wire that weighs 7.5 kilograms how many meters of wire will be in a new shipment that weighs 502.5 kilograms?
Number of rolls in the new shipment = 502.5/7.5Length of the new shipment = 50 x (502.5/7.5) = 3,350 meters
Can copper and alluminium wire of same length and diameter have same resistance?
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
A piece of copper wire was cut into n equal parts these parts are connected in parallel how will the resistance of the parallel combination compare with the resistance of the wire?
The resulting resistance of the parallel combination will be the resistance of the original wire divided by n squared.
What would reduce resistance in a copper wire?
Reduce the resistance:-- Use a shorter piece of wire.-- Use thicker wire.-- Cool the wire.Increase the resistance:-- Use a longer piece of wire.-- Use thinner wire.-- File a nick in the piece of wire you have.-- Stretch the wire.-- Heat the wire.
What is the resistance of a 6 000 foot piece of 1 0 copper wire?
The answer depends on the cross sectional area of the wire. This is not given.
Does a longer wire equal resistance?
Wire is not equal to resistance. If you have two pieces of wire with the same thickness, composition, and temperature, the longer piece has higher electrical resistance.
Which material has a greater resistance aluminum or copper wire?
Aluminium wire has high resistance than Copper.
Does long wire have a lower or higher resistance than short wire?
A long piece of wire will have more resistance in it than a shorter one of the same material.
What has the lowest resistance copper wire or iron wire?
Copper wire. .wikipedia.org/wiki/Electrical_resistivity_and_conductivity
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
Does a thin wire has more RESISTIVITy or a thin wire of the same material?
Resistivity is a property of the material only, not of the dimensions of the wire. The resistance of a wire is the resistivity times the length divided by the cross-section area. So a long wire has more resistance, a thicker wire has less resistance, even if they are both made of copper with the same resistivity.
Does a short copper wire have more resistance then a long one?
No. Other things being equal, a long wire has more resistance than a short wire.
What has more resistance a nichrome wire or a copper wire?
Nichrome wire has such high resistance that it is used to convert electrical energy into heat. Many heating elements are made from nichrome. Copper wire has the best conductivity, for the price, of any metal.
