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.
The formula for the area of the square is length multiplied by width.
This formula is used to calculate the volume of a rectangular prism.
length x width = area (sq. foot)
It is called area. The formula for are is length x width, or l x w.
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.

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 know that each 'wrap' or turn of wire in the coil has to go all the way around the coil-form, and you know how to calculate the distance around a circle. So all you have to do is count the number of times the wire goes around the coil, measure the coil's diameter, calculate its circumference, and multiply that by the number of turns in the coil.
To find the length of the wire, we need to calculate the volume of the copper sphere first. The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. Substituting r = 3 cm, we find the volume of the sphere to be approximately 113.1 cm³. Next, we need to find the volume of the wire. Since the wire is cylindrical, its volume can be calculated using the formula V = πr²h, where r is the radius and h is the height (length) of the wire. Given the diameter of the wire is 0.4 cm, the radius is 0.2 cm. Assuming the wire is very long compared to its diameter, we can approximate the wire as a cylinder and find its length by dividing the volume of the sphere by the volume of the wire. This gives us the length of the wire as approximately 565.5 cm.
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.
To calculate the sag between two transmission poles, you can use the catenary equation which considers the weight of the span wire and the tension in the wire. The formula takes into account the span length, weight per unit length of the wire, and the tension in the wire to determine the sag. It is important to ensure that the sag is within acceptable limits for safety and operational purposes.
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 calculate the area of a square, you multiply the length of one side by itself. The formula is: Area side length x side length.
