How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
What is the diameter of a circle with a area of 37.68?
The diameter of a circle with an area of 37.68 is 6.92
Does the area of a circle double if its diameter doubles?
The area is four times as large if the diameter doubles.The area of a circle is A = (pi)r2 or (pi)(diameter/2)2Since d is squared, it increases the area by the square of 2 if the diameter is doubled.Try calculating the area for a diameter of 2m, 4m and 8m to prove this.
What is the area of a circle that is 8 feet in diameter?
A circle with a diameter has an area of 50.265486543928724876568901 sq. ft.
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Do thick wires have high or low resistance?
Low resistance.AnswerSince resistance is inversely proportional to the cross-sectional area of a conductor, increasing the diameter ('thickness') of a conductor will reduce its resistance.For example, doubling the diameter of a circular-section conductor will quadruple its cross-sectional area, and reduce its resistance by one quarter.
What is the area of a conductor with a diameter of 100 mils?
To find the area of a conductor with a diameter of 100 mils, first convert the diameter to radius by dividing by 2, resulting in a radius of 50 mils. The area ( A ) can be calculated using the formula for the area of a circle: ( A = \pi r^2 ). Thus, the area is approximately ( A \approx 3.14 \times (50 \text{ mils})^2 ), which equals about 7850 square mils.
What is the value of the resistance when both length and diameter are double?
Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.
Why the cable size is expressed in Sqmm not in diameter regardless of single or stranded conductor?
The cross-sectional area is one of the factors that determines how much current a conductor can carry -this is regardless of the shape of that conductor's cross section (many conductors are not circular). So the diameter is of not much interest.
When the diameter of a conductor is doubled what happens to its resistance?
Resistance will decreases... Because R is inversely proportional to Area of the conductor.AnswerIf the conductor has a circular cross-sectional area, then doubling the diameter will reduce the resistance to one quarter of its original distance. This is because area is proportional to the square of the radius, and resistance is inversely proportional to cross-sectional area.
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
What does 250kcmil AWG mean?
It is a wire size, the equivalent cross sectional area in thousands of circular mils. e.g. 500 MCM or kcmil = 500,000 circular mils. The circular mil is a unit of area used especially when denoting the cross-sectional size of a wire. It is the equivalent area of a circle whose diameter is 0.001 (10-3) inch. AWG stands for American Wire Guage.
What is the skin effect in transmission lines?
It is the tendency of alternating current to flow more in the outer part of the conductor than in the centre. This reduces the effective cross-section area of the conductor. For this reason conductors with a diameter of more than about 30 mm are uncommon.
What is the area of a circle with a diameter of 9.4 m?
The area of a circle with a diameter of 9.4 m is: 69.4 m2
What size copper main bonding jumper is required based on the service entrance conductors being rated at 250 kcmil thwn-thnn copper?
A size 3/0 AWG copper main bonding jumper is typically required for service entrance conductors rated at 250 kcmil copper. This is based on NEC requirements for sizing the main bonding jumper to be at least 1/10th the circular mil area of the largest service entrance conductor.
What happens when doubling the area of a conductor?
Doubling the area of a conductor reduces the resistance by half. This is because resistance is inversely proportional to the cross-sectional area of the conductor. Therefore, doubling the area reduces the resistance, making the conductor more efficient in conducting electricity.
What are the factors affecting the resistance of conductors?
Conductor resistance = Conductor resistivity * Length of conductor / Cross sectional area of conductor. So. It is directly proportional to material & conductor length. And inversely proportional to the cross sectional area of conductor.
