How does the cross sectional area of wire affect resistance?

Other things being equal, more cross-sectional area will cause less resistance.


What is the relationship between resistance and cross-sectional area in a conductor?

The relationship between resistance and cross-sectional area in a conductor is inversely proportional. This means that as the cross-sectional area of a conductor increases, the resistance decreases, and vice versa. This relationship is described by the formula: Resistance (resistivity x length) / cross-sectional area.


Do bend in the wire effect the electric resistance?

Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.


Is the resistance of the wire directly or inversely proportional to the cross-sectional area of the wire?

The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.


How does a resistance of a wire depend on its radius?

Resistance is inversely-proportional to the cross-sectional area of a conductor. For example, doubling its cross-sectional area will halve its resistance, while halving its cross-sectional area will double its resistance.Since the cross-sectional area of a circular-section conductor is proportional to the square of its radius, doubling that radius will reduce its resistance by one quarter, while halving its radius will quadruple its resistance.


What 4 things affect resistance?

The four things that affect resistance are the material of the conductor, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor.


What effect will the cross-sectional area of the conductor have on the resistance of a conductor?

The cross-sectional area of a conductor is inversely proportional to the resistance of the conductor. Increasing the cross-sectional area decreases the resistance, as it allows more space for electrons to flow through, reducing collisions and increasing conductivity. Alternatively, decreasing the cross-sectional area increases resistance, as there is less area for electrons to flow through, leading to more collisions and increased resistance.


How does the 4 factors affect the resistance?

The four factors that affect resistance are material, length, cross-sectional area, and temperature. Resistance increases with longer length and higher temperature, and decreases with greater cross-sectional area and more conductive material. These factors impact the ability of a material to impede the flow of electrical current.


How does thickness of a wire affect resistance?

Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance. The resistance R = l p / A where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section. So R the resistance is inversely proportional to A the area of cross-section. If R increases


When the length and area of cross section both are doubled then its resistance?

The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
