How does the resistance of a wire vary with its area of cross section B diameter?

By increasing the area of cross section, the resistance will decrease. By increasing the diameter, the resistance will decrease.

How does resistance of a wire is influenced by its length and area of cross section?

More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.

How does the resistance of the wire vary with its length?

Resistance is directly proportional to the length and inversely proportional to the area of cross section.

How is the resistance of a resistor related to its length and cross-sectional area?

Resistance is proportional to resistivity and length, and inversely proportional to cross sectional area.

How does the resistance of wire change when its length is tripled?

Resistance becomes 1/9 th. Resistance becomes 3 times.

What is the relationship between resistivity and resistance of the wire?

The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity. The resistivity is a characteristic of the material used to fabricate a wire or other electrical component, whereas the resistance is a characteristic of the wire or component.

How does resistance vary length and area?

Electrical resistance is directly proportional to the length (L) of the conductor and inversely proportional to the cross-sectional area (A). Resistance is inversely proportional to the area of cross-section. When the area of cross-section increases the resistance decreases and vice versa.

How does resistance vary with area?

Resistance is inversely proportional to area of cross section. larger will be the area lower will be the resistance and vice versa. this is because through a conductor with large area of cross section current can easily flow and hence resistance is low.

How does area of cross section of resistance?

We can see from the graph that as the cross section area, A, increases, the resistance, R, decreases. A thicker wire has a smaller resistance than a thin wire. A more detailed investigation shows that resistance and cross section area are inversely proportional .

How does resistance depend on length and area?

a) Length: Resistance is directly proportional to the length of the conductor. Resistance is inversely proportional to the cross-sectional area of the conductor. Thus, the resistance of the conductor decreased with the decrease in cross-sectional area.

How does resistance depend on area?

Resistance is Inversely proportional to cross sectional area.. Explanation: this is because, if area of cross section increases, there will be more area for flow of electrons in the direction opposite to current.. and thus resistance (opposition of flow of electrons) becomes low.

How does the resistance of a wire change when its length is tripled its diameter is triple its material is changed to one whose resistivity is three times?

Solution : Resistance becomes 3 times.

How does the resistance of a wire vary with its cross sectional?

How does the resistance of a wire vary with its cross sectional area. > How does the resistance of How does the resistance of a wire vary with its cross sectional area. It is inversely proportional to the area of cross section of the wire.

How does the volume of a wire affect the resistance?

But in general as the volume of the wire increases the resistance lowers in a linear way. Double the area and half the resistance. (note double area, not double the diameter) As to length the resistance is directly due to the length, double the length double the resistance.

What is the relationship between resistance and length of conductor?

The resistance of a conductor is directly proportional to its length (L) as R ∝ L. Thus doubling its length will double its resistance, while halving its length would halve its resistance. Also the resistance of a conductor is inversely proportional to its cross-sectional area (A) as R ∝ 1/A. Please log inor registerto add a comment.

What happens when a wire is stretched?

A wire of length L and resistance R is stretched so that its length is doubled and the area of cross-section is halved. askedMar 7, 2018in Scienceby shabnam praween(137kpoints)
