What happens to the resistance when length is doubled n area is quadrupled?
It is halved.It is halved.It is halved.It is halved.
What happens to the resistance of a conductor when the length of the conductor is reduced to half?
If the length of the conductor is halved, the resistance of the conductor also decreases by half. This is because resistance is directly proportional to the length of the conductor. Shortening the length leads to fewer collisions between electrons and reduces the overall resistance.
How does resistivity vary if area is halved?
If the area is halved while keeping the length and resistivity constant, the resistance will double. This is because there is less space for the electrons to flow through, increasing the collisions encountered, hence increasing the resistance.
What is the Change in resistance of wire when its length is double?
Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.
What factors effect the resistance of a wire?
Its elemental makeup. Its' diameter and its' length.
Length of the spring is halved then the spring constant becomes?
If the length of the spring is halved, the spring constant remains the same. The spring constant is determined by the material and shape of the spring, and is not affected by changes in length.
What are the rules for electricity resistance?
Resistance of a conductor is defined by the specific resistivity, area of cross section and the length of the conductor. R = rL/A, where R is resistance in OHMs, r is specific resistance, L length in mm, A is area of cross section in sq mm
Three ways which resistance of a wire can be increased?
You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).
What happens to the area of a rectangle if the length decreases by one-half?
The area is directly proportional to both the length andwidth of a rectangle. Thus if one is halved then the area is also halved.
How do you work out resistance with voltage and joules?
Resistance of a conductor is defined by the specific resistivity, area of cross section and the length of the conductor. R = rL/A, where R is resistance in OHMs, r is specific resistance, L length in mm, A is area of cross section in sq mm
