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.

At 0 degrees Celsius, the resistance in the wire is 1000 Ohm.

No, there'll be a difference in resistance. Aluminum has more resistance than copper does, although it still a low resistance wire.

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.

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.

Very much so. Copper wire has a low resistance to electricity and makes an excellent conductor.

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.

No. Other things being equal, a long wire has more resistance than a short wire.

Copper wire has low resistance, so it is unable to produce enough heat to glow.

Because Nichrome has a high resistance and copper has a low resisitance.

Generally a larger diameter copper wire would create the least resistance to electron flow. Copper is the most conductive and is widely used.

Copper wire has apparently lower resistance than the reed switch. The lower electric resistance, the higher electric current.

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 and is also produced by a 3 degree C temperature rise in copper.

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.

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

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.

A wire with low resistance. To obtain the lowest resistance, the wire must be -- thick -- a good conductor; silver, copper, etc. -- cold

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.

Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
