Does diameter affect resistance?

The greater the diameter of the cylinder, the more current it can carry (again similar to the flow of fluid through a pipe). In fact, R is inversely proportional to the cylinder’s cross-sectional area A. The larger its cross-sectional area A, the smaller its resistance.

Does resistance increase with wire diameter?

As the diameter of the wire increases, the resistance decreases. In fact, if we double the cross-sectional area then the resistance halves. This means that resistance is inversely proportional to the area of the wire.

How does the diameter and length of the wire affect resistance?

In a parallel circuit, the more resistors you have in parallel the more the resistance decreases, because it increases the number of pathways for the electricity to flow. This would be similar to increasing the diameter of a single piece of wire. The greater the diameter the lower the resistance.

Why does resistance decrease with diameter?

The resistance is inversely proportion to the area of the conductor. The area is proportional to the square of the diameter. Therefore, the resistance is inversely proportional to the square of the diameter of the conductor. The resistance gets decreased as the diameter is increased.

What is the relationship between resistance and area?

The relationship between resistance and the area of the cross section of a wire is inversely proportional . When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.

Why does the diameter of the wire affect the resistance?

The longer a wire is the more resistance it has due to the longer path the electrons have to flow along to get from one end to the other. The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through. This will continue to apply no matter how thick the wire is.

What is the relationship between resistance and length?

The relation between length and resistivity is given by the resistivity formula. Resistance is directly proportional to the length. This means that any change in length of the material will change its value of resistance.

Why does the resistance increases with length?

When electrons start to move, they get scattered from the nuclei present in the material which is the wire made from. This process creates the resistance. Thus, when the length of the wire increases, the amount of particles scattered from the nuclei increases which also increases the resistance.

What is the relationship between the resistance and the thickness of the conducting putty?

The resistance of the thin wire is greater than the resistance of the thick wire because the thin wire has fewer electrons to carry the current. Therefore, for thinner pieces of conducting putty we have the larger resistance and for the thicker pieces of conducting putty we have the lower resistance.

What determines the resistance of a wire?

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. The resistance of a conductor, or circuit element, generally increases with increasing temperature.
