What happens to the resistance if area of cross section is doubled?

On increasing the area of cross-section, resistance decreases. This is because resistance is inversely proportional to area.

What happens to the resistance of a conductor if the area of cross section is doubled without changing the length?

Thus, the above equation shows that the length of the conductor and the cross-section of the conductor are doubled, then the resistance of the conductor will remain the same, there is no change in the resistance of the conductor.

What happens to the resistance of a conductor if its area of cross section is decreased?

S: Value of resistance decreases with decrease in area of cross-section.

What is the effect of area of cross section on the resistance of a conductor How does the resistance of a wire change when area of cross section is tripled?

The resistance of a conductor decreases with increase in cross-sectional area.

What happens to the resistance of a conductor if its area of cross section is reduced to half and its length is doubled?

The resistance of conductor is directly proportional to length and inversely proportional to area of cross section. When the length is doubled the area of cross section also gets doubled. When the area of cross section is halved then resistance becomes double .

What happens to resistance of a conductor when its area of cross section is increased class 10?

What is the effect of area of cross-section on the resistance of a conductor How does the resistance of a wire change when area of cross-section is tripled?

What happens to the resistance of a conductor if its area of cross-section is decreased?

What happens to the resistance when the cross section is doubled?

Resistance is proportional to length ; Therefore, when length is doubled the resistance will become 2 times to 2R Resistance is inversely Proportional to Cross section area; Therefore, when cross section is doubled resistance becomes half to 1/2R Now you are not changing the material so p remains same.

What happens when you double the cross sectional area of a wire?

So, doubling the cross sectional area of (circular) wire means increasing radius of wire by sq. root of 2 or simply 1.4142. If the length and diameter of a conductor is double, then what will be its resistance? If the conductor is the same, and thus has the same resistivity, and the conductor is cylindrical, then the resistance will halve.

What happens to the resistance of a conductor when length is doubled?

The resistance of such a conductor is therefore doubled if its length is doubled. However, its resistance becomes a quarter if its diameter is doubled (because of which its area of cross section becomes a quarter).

What happens if you double the length of a material?

If both length and cross sectional area are doubled, the value nullifies and the resistance remains the same. But, remember that L is in terms of metres and A is in terms of sq. metres.
