Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
What is the resistance of a 6 000 foot piece of 1 0 copper wire?
The answer depends on the cross sectional area of the wire. This is not given.
What happens to the cross-sectional area of metal wire if you double the diameter?
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
Why do you square the radius when finding the volume of a cylinder?
Because the volume of the cylinder is proportional to the cross sectional area of the cylinder. The cross sectional area is a circle and the area of a circle is pi*r2.
Which has the greatest cross sectional area?
9 AWG
How does cross sectional area affect resistance?
the larger the cross sectional area, the smaller the resistance
Do bend in the wire effect the electric resistance?
Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.
Is the resistance of the wire directly or inversely proportional to the cross-sectional area of the wire?
The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.
How does a resistance of a wire depend on its radius?
Resistance is inversely-proportional to the cross-sectional area of a conductor. For example, doubling its cross-sectional area will halve its resistance, while halving its cross-sectional area will double its resistance.Since the cross-sectional area of a circular-section conductor is proportional to the square of its radius, doubling that radius will reduce its resistance by one quarter, while halving its radius will quadruple its resistance.
What 4 things affect resistance?
The four things that affect resistance are the material of the conductor, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor.
What effect will the cross-sectional area of the conductor have on the resistance of a conductor?
The cross-sectional area of a conductor is inversely proportional to the resistance of the conductor. Increasing the cross-sectional area decreases the resistance, as it allows more space for electrons to flow through, reducing collisions and increasing conductivity. Alternatively, decreasing the cross-sectional area increases resistance, as there is less area for electrons to flow through, leading to more collisions and increased 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.
How does thickness of a wire affect resistance?
Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance. The resistance R = l p / A where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section. So R the resistance is inversely proportional to A the area of cross-section. If R increases
When the length and area of cross-section both are doubled then its resistance?
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
When the length and area of cross section both are doubled then its resistance?
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
What are the factors that affect resistance?
The factors are: length, cross-sectional area and nature of substance.
Does resistance increase as the cross-sectional area of the wire?
No, resistance decreases as the cross-sectional area of the wire increases. This is because a larger cross-sectional area provides more pathways for the electrons to flow through the wire, resulting in less resistance.
