If you increase the length of a wire while keeping the volume constant, the wire's thickness will decrease proportionally. This is because the volume of the wire is distributed over a longer length, resulting in a thinner 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.
Actually resistance is directly proportional to the length provided area remains constant. But as we stretch the wire only its volume would remain constant. So its area is to be decreased as length increases. V = pi r^2 * L Now we have R = K * L / pi r^2 Multiplying numerator and denominator by L we get R = K/V * L^2 So resistance is found to be proportional to square of length Hence as length gets increased by 2 times, its resistance value would increase by 4 times.
The thickness of the wire (resistance) and length of the wire can affect the brightness of the bulb. Thicker wire has less resistance, allowing more current to flow and producing a brighter bulb. Shorter wire lengths also reduce resistance, resulting in a brighter bulb due to more current flowing through it.
Decreasing the length or increasing the thickness of the wire would cause its resistance to decrease.
Assume that the increase in length is achieved by uniform reduction in the cross-sectional area of the wire. Then an increase in length by 4 times will result in the cross sectional area being reduced to a fifth of it original value. This will increase the resistance to five times its previous value.

#1). Thinner wire.Either replace a wire with one composed of thinner material, orstretch the existing wire slightly so that it becomes thinner.#2). Longer wire of the same thickness.

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 thickness of the wire (resistance) and length of the wire can affect the brightness of the bulb. Thicker wire has less resistance, allowing more current to flow and producing a brighter bulb.

When copper wire is heated, the atoms within the wire vibrate more vigorously, leading to an increase in kinetic energy. This causes the wire to expand slightly in length and thickness. If heated excessively, the wire can eventually melt and transform into a liquid state.
capacitance also increase
A copper wire will allow more electric current to pass through compared to a steel wire of the same thickness and length. This is because copper has lower resistance to the flow of electricity, resulting in better conductivity.
If both the diameter and length of a wire are quadrupled, the resistance of the wire will increase by a factor of 16. This is because resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire, which is determined by the diameter. By quadrupling both, the resistance will increase by 4^2 = 16 times.
