There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.

∙ 14y agoThe formula for the area of the square is length multiplied by width.
This formula is used to calculate the volume of a rectangular prism.
It is called area. The formula for are is length x width, or l x w.
length x width = area (sq. foot)
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
how to calculate area of a wire
To calculate the resistance of a single core wire, you will need to know the resistivity of the material the wire is made of, the length of the wire, and the cross-sectional area of the wire. You can use the formula: Resistance = resistivity * (length / cross-sectional area). Plug in the values for the resistivity, length, and cross-sectional area to find the resistance of the 70mm^2 single core wire.
Formula to calculate length of spiral reinforcement in columns
To calculate the length of the wire, you can use the formula: resistance = resistivity * (length / cross-sectional area). First, calculate the cross-sectional area of the wire using the formula for the area of a circle (A = π * r^2). Then, rearrange the formula to solve for the length of the wire.
You can use the formula for the length of a helix: length = (number of turns) x (coil diameter) x (π). Count the number of turns in the coil, measure the outer diameter of the coil, and use these values in the formula to calculate the approximate length of the wire.
To find the length of wire that can be made from the solid copper sphere, first calculate the volume of the sphere using the formula V = (4/3) * π * r^3. Then, find the volume of wire using the formula V = π * (r/2)^2 * h, where h is the length of wire. Equate the two volumes and solve for h to find the length of wire.
To calculate the length of the wire needed, you first find the cross-sectional area of the wire using the formula for the area of a circle (A = πr^2), where the radius is half the diameter. Then, you can calculate the length using the formula R = ρ * (L/A), where R is the resistance, ρ is the resistivity of aluminum, L is the length of the wire, and A is the cross-sectional area. Substituting the values of 1 ohm for resistance, 2.59mm for diameter, and 2.8x10^-3 ohm m for resistivity, you can solve for the length of wire needed.
The resistance of a wire is not sufficient information to determine its diameter. The diameter of a wire is typically needed to calculate its resistance using the formula R = ρ*L/A, where ρ is the resistivity, L is the length, and A is the cross-sectional area. You would need to know the resistivity and material of the wire to calculate its diameter.
You need also to know the resistance of the cable. First you establish what the current of the load is. Then from that you calculate the wire size. From a wire size chart you find the wire resistance. Then use the formula I (squared) x R.
i dont know.... plz tel how to calculate
To find the length of coiled wire in the slinky, calculate the circumference of each circle by using the formula 2πr. Then, multiply this by the number of circles (assuming they are all the same size) to get the total length of wire used. Finally, convert the total length to inches if needed.
You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage
