The formula for the area of a square is s2 (sides squared)
The formula for the cross-sectional area of a coin is calculated using the formula for the area of a circle, which is A = πr^2. In this formula, A represents the area, π is a constant approximately equal to 3.14159, and r is the radius of the coin. By substituting the radius of the coin into the formula, you can calculate the cross-sectional area of the coin.

the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
Area = Length * width
The ddiameter of No. 14 wire is 64 mils. What is its area in CM and in SM?
To calculate the area of a multi-strand wire you use the formula D = square root of (4S divided by pi), where S equals the number of strands times the area of one strand.
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. This means that for a given material, a longer wire will have higher resistance and a thicker wire will have lower resistance. The relationship is described by the formula: Resistance = resistivity x (length / cross-sectional area).
A piece of wire stretched such that its length increases and its radius decreases will tend to have its resistance increase. The formula for this is: R = ρL/A where ρ = resistivity of the material composing the wire, L = length of the wire, and A = area of the conducting cross section of the wire. It can easily be seen that as area decreases resistance gets higher. In the case proposed the wire length is not reduced as it is stretched to reduce the area, this increases the resistivity as well.
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.
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.
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
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.
Bends in a wire do not affect its resistance because the cross-sectional area and length of the wire remain the same regardless of the bends. Resistance is determined by these two factors, according to the formula R = ρ*(L/A), where ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area. As long as these parameters remain constant, the resistance of the wire will stay the same.
No
Increasing the length of the wire will not reduce resistance in a copper wire. In fact, resistance is directly proportional to the length of the wire according to the formula R = ρ * (L/A), where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
