What is the area formula for a square?
The formula for the area of a square is s2 (sides squared)
What is the formula of cross sectional area for a coin?
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 double the area of a circle
What is the formula for finding the area of an ellipse?
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
What is the formula of area of path?
Area = Length * width
Write a formula used to find circular mil area?
The ddiameter of No. 14 wire is 64 mils. What is its area in CM and in SM?
How do you calculate the area of the multi strand wire?
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.
Calculate cross sectional area of wire?
If the wire has a circular cross-section - the usual case - use the formula for the circle: pi x radius squared.
How does the resistance of a wire depend on its dimensions?
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 is stretched such that its length increases and its radius decreases the resistance of the wire will tend to?
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.
How do you calculate resistance of 70mm2 single core 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.
What is the formula to calculate length of the 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.
Would have the same resistance as a copper wire that is 4 m long and has a cross-sectional area of 0.066 cm2?
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.
A copper wire has diameter 0.5mm and resistivity of 1.61010101010101010 ohm meter what will be the length of the wire to make its resistance 10 ohm?
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.
Why bends in a wire do no affect its resistance?
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.
What would not reduce resistance in the copper wire?
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.
Is there a formula to figure out the rough amount of wire you will need to wire your basement?
No
