Volume is the quantity of three-dimensional space enclosed by a closed surface and it is measured in cubic units. Given here is the formula to calculate the volume of a conductor (wire or cable) in a transformer line. The volume of a conductor formula uses the parameters area and length of the conductor to determine the volume.
A thin wire has length of 21.7 cm and radius 0.46 mm. Calculate the
Answer. As R → ∞, Equation 1.6.14 reduces to the field of an infinite plane, which is a flat sheet whose area is much, much greater than its thickness, and also much, much greater than the distance at which the field is to be calculated: →E = lim R → ∞ 1 4πϵ0(2πσ − 2πσz √R2 + z2)ˆk = σ 2ϵ0ˆk.

There is no change in volume of a wire due to change in its length of stretching. The Poisson's ratio of the material of the wire is: A 0.5 B - 0.50 C 0.25 D - 0.25 Solution Verified by Toppr The correct option is A 0.5 Volume of a wire of radius r and length l is, V = πr2l ∴ dV = 2πrldr+πr2dl 0 = 2πrldr+πr2dl (dv = 0, as volume is unchanged)

volume=1/3 × π × 4(0.2 2 + 0.2 × 1.5 + 1.5 2) = 10.849 in 3. Ellipsoid. An ellipsoid is the three-dimensional counterpart of an ellipse, and is a surface that can be described as the deformation of a sphere through scaling of directional elements. The center of an ellipsoid is the point at which three pairwise perpendicular axes of symmetry.

Answer Verified 296.9k + views Hint: It is said that a copper rod is converted into a wire. So the volume of the copper rod and wire will be the same. The volume of these is similar to that of a cylinder. Find the volume of copper rod and equate it to the volume of wire, to get the diameter of wire. Complete step-by-step answer:

The calculator is designed to accept the total line voltage and current of the combined three cables. The equation for the area of a single wire is modified to: A = \frac {\sqrt 3 I \varrho L} {V} A = V 3I ϱL. The factor of \sqrt 3 3 is needed to convert between the system's phase current and line current.
