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.
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.
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.
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.
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 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.

The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).

Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.

according to ohm's law V = IR or I = V/R 1. so current is directly proportional to potential difference across the wire 2. and it is inversely proportional to resistance of wire.
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
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.
