What is the resistance of copper wire at 90 degrees Celsius?
I`m Sorry But I`ve Given This A Couple Hours Calculating And I Have Yet To Get An Answer At 90 C Temp. Forgive Me. Depends On The Length Of The Wire And The Guage.

The resistance of a tungsten light bulb is greater than the resistance of a copper wire. In addition, as the bulb get hotter, the resistance increases, due to the positive resistance to temperature coefficient of the filament. Read More
The electrical resistance of a material is proportional to its length, and inversely proportion to its cross-section. So a long thin copper wire would have the greater resistance. Read More
Very much so. Copper wire has a low resistance to electricity and makes an excellent conductor. Read More
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. Read More
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
Copper will. Read More
No. Other things being equal, a long wire has more resistance than a short wire. Read More
Hot wire strip heaters are used for usually sealing two pieces of poly together to form a bag or band around an object. Due to the variable types of poly used and different manufactures specifications , one heat can not be used for all occasions. There is a thermostat that is added in line with the hot wire to control the temperature of the wire. This thermostat limits the heating of the wire so as… Read More

The resulting resistance of the parallel combination will be the resistance of the original wire divided by n squared. Read More
Copper wire has low resistance, so it is unable to produce enough heat to glow. Read More

Because Nichrome has a high resistance and copper has a low resisitance. Read More
Generally a larger diameter copper wire would create the least resistance to electron flow. Copper is the most conductive and is widely used. Read More
Copper wire has apparently lower resistance than the reed switch. The lower electric resistance, the higher electric current. Read More
If a wire has insulation that allows it to operate in a temperature of up to 194 degrees Fahrenheit what temperature will the wire operate uopt to in degrees celsius?
Use the formula: C = (5/9)(F-32) The answer is 90 degrees Celsius. Read More
The main difference is in the price. Oxygen-free copper is sold to people with plenty of money for loudspeaker wire, but provided the wire has less resistance than one tenth of the speaker resistance (usually 4 or 8 ohms), the resistance of the wire is immaterial, and ordinary copper wire is perfectly all right. Highly refined copper has about 1% better conductivity than the usual variety. That difference in conductivity is insignificant for audio use… Read More
Energy which is dissipated, by the resistance in the wire used in a coil, in an electrical device such as a transformer is known as copper loss. The formula is, Copper loss = amps squared x resistance. Read More

If two copper wires are the same length but different thicknesses the thinner or thicker wire has greater resistance?
The thinner the wire, the higher the resistance. The thicker the wire, the resistance decreases. Think of it this way. The thick wire has more room for electrons to jump around, but the thin wire has less room. Read More
Is either; A. the length of the wire B. the diameter of the wire c. the location of the wire D. the temperature of the wire Read More
Two wires are of same materials but of different lengths and areas of cross sectional will their resistivities be same or different?
The resistance of a material depends upon the following: the length , the cross sectional area, type of material and temperature. In electrical science the following obtains. Two copper wires of different lengths and different "csa" will not have the same resistance. The resistance of the wire is directly proportional to the length and inversely proportional to the "csa". The temperature of the conductors must be the same and the copper material of which they… Read More

A wire with low resistance. To obtain the lowest resistance, the wire must be -- thick -- a good conductor; silver, copper, etc. -- cold Read More
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. Read More
Resistance will only be reduced by changing the thickness of the wire or the wire's temperature. It's apparent impedance can be changed by placing it in an electric field as well. Read More

The current that you can put through a wire depends on the voltage you apply and the resistance of the wire. In fact; current = voltage/resistance Current is the sum effect of electrons moving through the wire. When the wire heats up, for example, by a torch, it causes increasing chaos in the wire, or entropy. This chaos causes the electrons to bump around more than before. Therefore, flow is with less ease. This means… Read More

The amperage rating of a copper wire is related to its resistance and to the type of insulation used (i.e., what temperature the insulation can handle) and the ambient temperature. The fatter the copper wire, the more amps it can handle, everything else being equal. A mineral-insulated wire, buried underground, would handle more amps than a similarly sized copper wire in thermoplastic insulation in air. There are electrician charts available to determine the MINIMUM size… Read More
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire. Read More
