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.
Two reasons:Mostly a stranded wire is far more flexible than a solid one and less likely to break after repeated flexing.At AC frequencies in the RF range an effect called the "skin effect" starts to become significant, current flow restricts itself to the skin of the conductor and the wire resistance rises. Stranded wire offers more skin and thus reduces the wire resistance again.

The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.
Increase the voltage applied to the wire. Decrease the resistance of the wire.
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.
The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.
You could increase the length of the wire or decrease its thickness to increase resistance in the electric circuit. Both of these changes will hinder the flow of electrons through the wire, resulting in higher resistance.
If a resistive wire is elongated, its resistance will increase. This is because the longer length of wire will result in more collisions between electrons and the wire's atoms, leading to higher resistance. The resistance of a wire is directly proportional to its length.
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.
You don't specify what you are referring to. However, if your question relates to resistance in general, then you should know that resistance is directly-proportional to the length of a conductor and to its resistivity, and inversely-proportional to its cross-sectional area. Resistivity is a characteristic of the material from which a conductor is made, and varies from one material to another.This means that you can increase resistance by increasing the length of a conductor, or by decreasing its cross-sectional area, or by selecting a conductor manufactured from a material with a greater resistivity (e.g. by using aluminium rather than, say, copper).
You can increase the current in a wire by increasing the voltage applied across it or by decreasing its resistance. Additionally, increasing the cross-sectional area of the wire can also help facilitate higher current flow.
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
Bends in a wire do not affect its resistance because the cross-sectional area and length of the wire remain the same regardless of the bends. Resistance is determined by these two factors, according to the formula R = ρ*(L/A), where ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area. As long as these parameters remain constant, the resistance of the wire will stay the same.
