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.
length area and material
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.
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!
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
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.
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.
it depends on:-1. no. of turns of the wire

the resistance is depends on the type of the metal and ith length
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.
"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.
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
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).
The answer depends on the cross sectional area of the wire. This is not given.
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.
A diode is an electronic component with the characteristic that its resistance is not constant, but depends on the magnitude of the current through it. An ideal diode has zero resistance to current in one direction, and infinite resistance to current in the reverse direction.
