If wires are made from the same material and are the same length which would have greater resistance?
The wire with smaller diameter (thinner wire) will have greater resistance. This is because resistance is inversely proportional to the cross-sectional area of the wire. Thinner wires have smaller cross-sectional area, leading to greater 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.
What happens to the resistance of a wire as it's length increases?
Other things being equal, a greater length will result in more resistance.
Is electric resistance greater in a short fat wire of a long thin wire?
Electric resistance is greater in a long thin wire compared to a short fat wire, due to the higher resistance associated with longer wires and thinner cross-sectional areas. Resistance is determined by the material's properties and dimensions, with length and cross-sectional area being key factors affecting resistance.
How does a wire's cross section affect resistance?
A wire with a larger cross section has lower resistance because there is more space for the electrons to flow through, reducing collisions. A smaller cross section increases resistance as there is less space for the electrons to move, causing more collisions and therefore higher resistance.
Does thickness of a metal affect its electrical resistance?
Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.
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).

Why does a 3 pin plug have big ground pin?
Resistance =pl/a where a is "area". And area is directly propotional to lenght and thickness. so if the area is greater mean resistance is less. and resistance is inversly proptional to current. so it will act as low resistance path for neutral current.

Resistance increases with longer length and higher temperature, and decreases with greater cross-sectional area and more conductive material.

When chip thickness ratio greater than 1?
When Rack angle is zero... Chip thickness ration is going to be greater.
Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
What happens to the resistance of a wire as it's length increases?
Other things being equal, a greater length will result in more resistance.

What is the disadvantages of Brinell hardness test?
The depth of impression must not be greater than the thickness of the test piece (material cannot be too thin). It cannot measure on cylindrical shaped objects, and the size of ball indentor used will give different readings.
How does a wire's cross section affect resistance?
A wire with a larger cross section has lower resistance because there is more space for the electrons to flow through, reducing collisions. A smaller cross section increases resistance as there is less space for the electrons to move, causing more collisions and therefore higher resistance.
How will the breaking stress be affected if the thickness of the rubber bands is increased?
Increasing the thickness of the rubber bands will generally increase the breaking stress. This is because thicker rubber bands have more material, which provides greater resistance to deformation and ultimately, a higher breaking point. The relationship between thickness and breaking stress is typically linear, meaning that as the thickness increases, the breaking stress will also increase proportionally. However, it is important to note that other factors such as the material composition and manufacturing process of the rubber bands can also influence breaking stress.
