What else can I help you with?
Does resistivity depend on length and area of the cross section of the material?
No. Resistivity is a material constant, defined for a standard size of material. For another size of material, it can be calculated. Resistivity is the same for any piece of material; resistance can change.
Does resistivity depends upon dimension of the conductor?
Yes, resistivity does depend on the dimensions of the conductor. The resistivity of a material is an intrinsic property, but the resistance of a conductor is also influenced by its dimensions such as length, cross-sectional area, and shape. These dimensions affect the resistance of the conductor through the formula R = ρ * (L/A) where ρ is resistivity, L is length, and A is the cross-sectional area.
Would have the same resistance as a copper wire that is 4 m long and has a cross-sectional area of 0.066 cm2?
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
What is the resistivity of plastics?
The resistivity of plastics can vary depending on the type of plastic material. Generally, plastics have higher resistivity compared to metals, with values typically ranging from 10^12 to 10^20 ohm-meter. Conductive additives or treatments can be incorporated into plastics to lower their resistivity for specific applications.
When force acting on an area is doubled while area is halved what happens to pressure?
If the force acting on an area is doubled while the area is halved, the pressure remains the same. This is because pressure is the result of force distributed over an area, so as long as the force and area change proportionally, the pressure stays constant.
How does resistivity vary if length and area are doubled?
if length is doubled then resistivity increases&when area is doubled resistivity decreases.
How do you calculate a cross-sectional area When all you know is resistance resistivity and length?
I think the equation you are looking for is Resistance (ohms) = Resistivity * Length / Area or R=p*L/A. This is the resistance of a circular wire with cross-section of A, length of L, and material with resistivity p. So to get area: Area = Resistivity * Length / Resistance.
When will be the effect of Volume and Surface Area of Spherewhen cut in to two half?
The volume will be halved and the surface area will be halved but with the base area of pi*radius2 added to it
What happens to the resistance as the area increases?
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
Why does the electrical resistivity of a conductor does not depend on its dimensions?
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length
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 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.
Does resistivity depend on length and area of the cross section of the material?
No. Resistivity is a material constant, defined for a standard size of material. For another size of material, it can be calculated. Resistivity is the same for any piece of material; resistance can change.
Can you represent electrical conductivity by finding its electrical resistance?
Conductivity is the reciprocal of resistivity, and is expressed in siemens per metre (S/m). Resistivity and, therefore, conductivity vary with temperature so are usually quoted at a specified temperature.Resistance is expressed in ohms. If you accurately measure the resistance, length, and cross-sectional area of a conductor, then you could determine its resistivity and, from that, its conductivity.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
What is resistivity of material?
the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
What happens to the area of a circle whose radius is halved?
the area of the circle will be 1/4 of its original area
