Temperature, Length of wire, Area of the cross-section of wire and nature of the material.
Temperature: (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)
A: The magnitude of resistance is depend on cross section of the wire the material constructed with and the additional strands of wire involved
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.
Length, cross sectional area, temperature, whether annealed or not, impurities.

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.
What are three things resistance of a wire depends on?
The resistance of a wire depends on its length - longer wires have higher resistance. It also depends on the material of the wire - materials with higher resistivity have higher resistance. Lastly, the cross-sectional area of the wire affects resistance - larger cross-sectional areas have lower resistance.

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
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.
Does the resistance of a wire depend on the cross section area of the wire?
No, the resistance of a wire primarily depends on its length, resistivity, and temperature. The cross-sectional area of the wire influences the wire's resistance indirectly by affecting the wire's overall resistance. A larger cross-sectional area generally results in lower resistance due to increased conducting area for current flow.
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
What is the resistance value of 1 meter copper wire?
The resistance value of a 1 meter copper wire depends on its gauge (thickness) and temperature. For example, a 1 meter wire of 24-gauge copper has a resistance of about 25.67 ohms at room temperature. It is important to consider these factors when calculating the resistance of copper wire.
What does the resistance of the wire depend on?
The resistance of a wire depends on three main factors: its length, its cross-sectional area, and the material it is made of. Generally, longer wires have higher resistance while thicker wires have lower resistance. The material's resistivity also plays a significant role in determining the wire's resistance.
If you cut a wire what happend to resistance?
Cutting a wire will increase the resistance in the circuit because now the current cannot flow through the cut wire path, creating an open circuit. This results in higher resistance and lower current flow in the circuit.
What are the two factors of a wire that will alter its resistance?
The two factors that will alter a wire's resistance are its length and cross-sectional area. Increasing the length of the wire will increase its resistance, while increasing the cross-sectional area will decrease its 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.
