There are formulae, but it is much easier to simply use a "voltage drop calculator" (many interactive ones can be found online), plug in your values and increase your conductor size until the calculated voltage drop over the required distance, at 1.25 times the required load (80 percent design factor), does not exceed 5 percent (the allowed voltage drop in USA and Canadian electrical codes, other countries vary).
For instance, your example could use 14 AWG, giving you a 4.8 percent drop, or 12 AWG for a 3 percent drop (assuming copper). If you were to use aluminum, you would need the larger conductor.

When you are using distance formula you are calculating the length of a right triangle?
Yes when finding the lengths of lines on the Cartesian plane
How do you calculate the area of a trapezoid?
To calculate the area of a trapezoid, you can use the formula: Area = 0.5 * (sum of bases) * height. Simply add the lengths of the two parallel sides (bases) of the trapezoid, multiply the sum by the height, and then divide by 2 to find the area.
What are the factors that affect the resistance of a conductor?
The factors that affect the resistance of a conductor are the material it is made of, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher resistance.
What is the formula of trapizoide?
The formula for the area of a trapezoid is A = (a + b) * h / 2, where a and b are the lengths of the two parallel sides, and h is the height of the trapezoid.
What is the formula for a trazoid?
The formula for the area of a trapezoid is A = (1/2) * (a + b) * h, where 'a' and 'b' are the lengths of the parallel sides and 'h' is the height of the trapezoid.
How do you find a permeter of a delta?
To find the perimeter of a triangle (often referred to as a "delta" in some contexts), you simply add the lengths of all three sides. If the side lengths are known as (a), (b), and (c), the formula for the perimeter (P) is (P = a + b + c). If only the coordinates of the vertices are given, you can calculate the side lengths using the distance formula and then sum them to find the perimeter.
How do you use the distance formula and slope formula to classify a quadrilateral?
To classify a quadrilateral using the distance formula and slope formula, first calculate the lengths of all four sides using the distance formula, which is given by ( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ). Next, determine the slopes of the sides using the slope formula ( m = \frac{y_2 - y_1}{x_2 - x_1} ). If the lengths of opposite sides are equal, the quadrilateral may be a parallelogram, and if the slopes of opposite sides are equal, it could be a rectangle or a rhombus based on the side lengths. Analyzing these properties will help classify the quadrilateral as a trapezoid, parallelogram, rectangle, rhombus, or square.
What is the circumference of a kite?
The circumference of a kite refers to the total distance around its outer edges. To calculate it, you add the lengths of all four sides of the kite. Since a kite has two pairs of equal-length sides, if you know the lengths of the pairs, the formula is: Circumference = 2(a + b), where 'a' and 'b' are the lengths of the two pairs of sides.
How do you calculate the perimeter of an isosceles?
To calculate the perimeter of an isosceles triangle, you add the lengths of all three sides. If the lengths of the two equal sides are each ( a ) and the base is ( b ), the formula is ( P = 2a + b ). Simply substitute the values of ( a ) and ( b ) into the formula to find the perimeter.
How do I Calculate the area of a trapezoid?
To calculate the area of a trapezoid, use the formula: Area = (1/2) × (b₁ + b₂) × h, where b₁ and b₂ are the lengths of the two parallel sides (bases) and h is the height (the perpendicular distance between the bases). First, add the lengths of the two bases, then multiply the sum by the height, and finally, multiply by 0.5 to find the area.
How do you calculate a parimeter?
That would be "perimeter". The perimeter is the distance around a figure, and it is calculated by adding the lengths of the different sides. For example, for a triangle, add the lengths of the three sides.
When you are using distance formula you are calculating the length of a right triangle?
Yes when finding the lengths of lines on the Cartesian plane
How can you find an object's weight from a lever?
To find an object's weight using a lever, you can use the principle of torque. By measuring the lengths of the lever arms on either side of the fulcrum, along with the distance from the object to the fulcrum, you can calculate the weight of the object. This is typically done using the formula: weight = force x distance.
How do you calculate are of trapezium?
The answer depends on what information you have. If you know the lengths of the two parallel sides (a and b) as well as the vertical distance between them (h), then Area = (a + B)*h/2 square units. Obviously, a different formula will be required if you have information about other aspects of the trapezium.
What is the square feet of a triangle that is 11.5 x 11.5 x 12?
I assume those would be the lengths of the three sides. If you know the lengths of the three sides of a triangle, you can use Heron's formula to calculate the area. For more details, read the Wikipedia article on "Heron's formula".
Do you calculate the volume of all solids by multiplying lengths times width times height?
yes sure by using the formula v=l*b*h
How do you calculate the manificiation?
Magnification is calculated using the formula: Magnification (M) = Image size (I) / Object size (O). It can also be expressed in terms of the focal lengths of the lens or mirror used, as M = - (Image distance (v) / Object distance (u)). A positive value indicates an upright image, while a negative value indicates an inverted image.
