It's dependent on the wire's composition. That is, what material it is made of.

Does heating a metal wire increase or decrease its electrical resistance?
it so increases it
The magnitude of the resistance of a wire depends on?
Temperature, Length of wire, Area of the cross-section of wire and nature of the material.
What are the car stereo wiring colour codes for a 1993 Renault clio?
The red wire is the positive wire. The black wire is the ground wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
Two ways resistance of a wire can be increased?
The resistance of a wire is determined by the following formula. R = (rho)L/A, where the greek letter rho (it looks like a p) is a value assigned to a material based on how resistive it is by nature, L is the length of the wire, and A is the cross-sectional area (AKA how thick the wire is). Increase the length, or change the material to something with higher restistivity. Hope this helps!
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
What do thick wires resist electricity?
Other things being equal, a thick wire has less electrical resistance than a thin wire.
Would thick wires tend to have the least amount of eletrical resistance?
Yes, the resistance is directly proportional to length of wire and inversely proportional Area, hence when Length of wire increases the resistance also increases and when Area increases the resistance decreases. This means a thick wire has least amount of Electrical resistance.
Which type of wires used in electrical works?
Electrical wire is the type of wire that is used in electrical equipment. To strip the wires, you need to use wire strippers. There is also special tape called electrical tape that is used to secure the wire.
How does temperature affect resistance of a wire?
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
What kind of wire would have the greatest electrical resistance?
Rubber wire!!!!
Why can't sodium be used in electric wires?
It can be used in electrical wires. Actually, in the future a lot of electrical wire may be made mostly of sodium. Google "lightweight composite electrical wire".
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.
Oxidized wire causes what?
increased electrical resistance
A wire that is what would have the greatest electrical resistance?
An insulator?
Why the value of armature resistance is low?
Because it is made of pure wire with nothing beyond its length and interaction with its neighboring wires to create resistance
Do thin wires have a greater or lesser resistance to electron flow than do thicker wires?
Thinner wire has greater resistance than thicker wire, assuming the same amount of current.
What type of resistance would exist for electrical timers?
none the resistance is in the wire not the timer
