∙ 9y agoTemperature: (An increase in temperature will increase the resistance)
Cross Sectional Area: (The larger the wire, the less resistance)
The length of the wire: (The longer the wire, the more resistance)
The material of the wire: (Some materials are better conductors than others, and this causes less resistance)

AnswerResistance depends upon the length, cross-sectional area, and resistivity of a conductor. It is directly-proportional to the resistivity and length, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, temperature indirectly affects resistance.

Electrical resistance in a wire depends on the wire's?
It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.
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 is the current through a wire that has a resistance of 30 ohms if the voltage is 45 volts?
If the resistance of the wire is 30 ohms and the voltage between the two ends of the wire is 45 volts,then the current through the wire isI = E/R = (45/30) = 1.5 amperes.
What part of the ohms scale of a meter are the most accurate resistance measurements made?
It really depends on what you are trying to get the resistance of. A piece of copper wire 30 feet long will only have a resistance of few ohms. A person can have a resistance of several million ohms. Making sure that your meter's leads are in good contact with whatever you are measuring is the best way to get an accurate reading.
Where does the magnitude of force depends?
it depends on:-1. no. of turns of the wire

What is the resistance of metal wire?
the resistance is depends on the type of the metal and ith length
What is a fundamental property of a wire that depends on a wire's moleculal structure and size?
Resistance
If you cut a wire what happend to resistance?
If you are talking about the total resistance in a circuit , it depends on the components in the circuit and the location of the cut.If you are talking about a single wire, the resistance becomes infinite (or close to it) when the wire is cut.
Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
What happens to resistance of the wire if the wire is short?
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
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.
Is resistance a vector?
A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
What are the factors on which the heat produced the electric current depends upon?
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.
How does the thickness of the wire affect resistance?
A thicker wire has less resistance than a thinner wire.
