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

How does cross sectional area affect resistance?

the larger the cross sectional area, the smaller the resistance


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.


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.


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.


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.


What are the factors that affect resistance?

The factors are: length, cross-sectional area and nature of substance.


Why do you need to ensure the cables are not twisted or plaited?

Because it would affect the Cross sectional area of the conductor therefore altering the resistance.


What effects the restance of an electrical conductor?

The resistance of an electrical conductor is primarily affected by its length, cross-sectional area, and the material it is made of. Longer conductors have higher resistance, while conductors with larger cross-sectional areas have lower resistance. Different materials have different resistivities, which also affect resistance.


Does resistance increase as the cross-sectional area of the wire?

No, resistance decreases as the cross-sectional area of the wire increases. This is because a larger cross-sectional area provides more pathways for the electrons to flow through the wire, resulting in less resistance.


What type of wire increases when it is made thinner?

Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!


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.
