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 happens to force when area is doubled?
If the area is doubled while keeping the force constant, the pressure exerted by the force will be halved. This is because pressure is defined as force divided by area, so doubling the area will result in a decrease in pressure.
What happens to the resistance of the conductor become longer but the diagram stays same?
If the length of the conductor increases while the cross-sectional area remains unchanged, the resistance of the conductor will increase. This is because resistance is directly proportional to length according to the formula R = ρ * (L/A), where ρ is the resistivity of the material, L is the length, and A is the cross-sectional area.
What is conductor area?
Conductor area refers to the cross-sectional area of a conductor, such as a wire or cable, that carries an electric current. It is typically measured in square millimeters or square inches and is an important factor in determining the current-carrying capacity and resistance of the conductor. A larger conductor area generally allows for more current to flow with lower resistance.
As the cross-sectional area of a conductor Increases the conductor..?
As the cross-sectional area of a conductor increases, its resistance decreases. This is because a larger area allows more electrons to flow through the conductor, reducing congestion and increasing conductivity. Consequently, the larger cross-sectional area decreases the resistance to the flow of current.
What is the effect on pressure of doubling the surface area on which a force is being exerted?
Doubling the surface area on which a force is being exerted reduces the pressure by half. This is because pressure is force divided by surface area. So, if the force remains the same while the surface area doubles, the pressure decreases.
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.
How does a resistance of a wire depend on its radius?
Resistance is inversely-proportional to the cross-sectional area of a conductor. For example, doubling its cross-sectional area will halve its resistance, while halving its cross-sectional area will double its resistance.Since the cross-sectional area of a circular-section conductor is proportional to the square of its radius, doubling that radius will reduce its resistance by one quarter, while halving its radius will quadruple its resistance.
What would be the effect of resistance of a conductor of doubling its diameter?
doubles
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.
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.
What happens to the area if the circumference of a circle is doubled?
Denote the original area by A, denote the new area by A', denote the original circumference by C, and denote the new circumference by C'. C=2*pi*r so C'=2C=2*pi*(2r). So doubling the circumference corresponds to doubling the radius. A=pi*r2. A'/A=pi*(2r)2/[pi*r2]=4. So doubling the radius quadruples the area.
What happens to the area of the circle when the diameter is doubled?
As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.
What happens to force when area is doubled?
If the area is doubled while keeping the force constant, the pressure exerted by the force will be halved. This is because pressure is defined as force divided by area, so doubling the area will result in a decrease in pressure.
What effect does doubling the base of a triangle have on the area?
Doubling the base of a triangle while keeping the height constant will double the area of the triangle. The area of a triangle is directly proportional to its base length, so increasing the base length by a factor of 2 will result in the area being multiplied by 2 as well.
Doubling the linear size of an object multiplies its area by?
Four.
How does doubling the side lengths of a triangle affect its area?
If you double them all it will be 4 times the area
What would the resistance of the wire if the resistance is 10 ohms be the same if it were twice as long?
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms
