You can increase the resistance in the wire, by doing any of the following:
Change its length, its cross-sectional area, or the material from which it is made (i.e. its resistivity). As temperature affects its resistivity, a change of temperature will also affect the resistance.
You can increase the resistance in the wire, by doing any of the following:
increased 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.
Resistance is increased so the light will be dimmer.

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!
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
The current at every point in the series circuit becomes slightly less, because the increased length of wire adds slightly more resistance to the loop.
There are two ways to elongate a piece of wire: Either stretch it, or attach another piece onto one end of it. Either way, the resistance will increase.
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).
There are three main factors that affect the resistance of a copper wire: Length of the wire: The resistance of a wire is directly proportional to its length. As the length of the wire increases, the resistance also increases. This is because the longer the wire, the more obstacles (collisions with electrons) the current has to overcome, resulting in higher resistance. Cross-sectional area of the wire: The resistance of a wire is inversely proportional to its cross-sectional area. As the cross-sectional area of the wire increases, the resistance decreases. This is because a larger cross-sectional area provides more space for the flow of electrons, reducing the resistance. Resistivity of the material: The resistance of a wire is also dependent on the resistivity of the material it is made of. Resistivity is an inherent property of the material and is a measure of how much the material opposes the flow of electric current. Copper has a relatively low resistivity compared to other metals, making it a good conductor and suitable for wiring applications. The relationship between these factors and the resistance of a copper wire can be expressed by the formula: R = ρ × (L / A) Where: R is the resistance of the wire ρ (rho) is the resistivity of the material (in this case, copper) L is the length of the wire A is the cross-sectional area of the wire By adjusting these three factors, you can control and manipulate the resistance of a copper wire to suit your specific needs in electrical and electronic applications.
1. Heavy, 2. Expensive, 3. Resistance.
A thicker wire has less resistance than a thinner wire.
