How does the resistance of a wire vary with its diameter?
At a greater diameter, the cross-section will also be greater, and therefore the resistance will be less. This assumes that other things are equal, of course.
Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?
No, a smaller diameter wire has a higher resistance. The 0.01 mm wire will have 1/100 the cross-sectional area of the 0.1 mm diameter wire, therefore the resistance will be 100 times as high.
A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
Its resistance would be half , 0.5 ohms is the answer.
Does the diameter of a deep water wave orbit decrease with depth?
Yes!
How does diameter of spring coil affect the force constant?
Keeping the rest characteristics of a coil the same, increasing coil diameter the spring constant decreases.
How is electrical resistance decreased?
Ways to reduce electrical resistance: increase the diameter of the conductor, decrease or increase the temperature of conductor (depending on its thermal characteristics), decrease the length of the conductor. A change in the material out of which the conductor is made can decrease resistance, too. And there is the phenomenon of superconductivity. In a simple circuit the resistance can be lowered by adding resistors in parallel. The total circuit resistance will then decrease. You can also reduce resistance by substituting resistors of lower value, or by adjusting a potentiometer, or pot, to a lower value.
When there is increased resistance then arteriolar constriction and pressure drops?
Resistance changes dramatically with changes in diameter of blood vessels (arterioles are one type of blood vessel). If you INCREASE the diameter of the arteriole, you DECREASE the resistance and thus DECREASE the blood pressure.
What is one thing that you could do to the wire used in a circuit to decrease the amount of resistance bulb by the wire?
Use thicker wire. Doubling the diameter gives one quarter the resistance.
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.
Why are the arterioles known as resistance vessels?
A. They distribute blood to various parts of the body. B. They contain a large quantity of elastic tissue. C. The contraction and relaxation of the smooth muscle in their walls can change their diameter. D. Their prime function is the exchange of nutrients and wastes between the blood and tissue cells.
If resistor X has the same length and is made of the same material as resistor Y but has twice the diameter. Resistor X has the blank resistance of resistor Y?
R = r*L/A where: R = resistance r = material resistivity L = length A = area Since you are doubling the diameter, you are increasing the area by a factor of 4, so Y will have 1/4 the resistance of X.
How do you increase or decrease the radius of a circle?
Increase or decrease the circle's diameter
Why car battery terminal heats up?
It's called resistance. Every electrical circuit has resistance to the "flow" of energy. This is how electric heaters work. Take a small diameter piece of wire, and put a lot of electrical current through it. The thinner the wire, the more it will heat up. If the wire is too thin, it will burn and break. This is why you want an adequate "gauge" of wire for your electrical needs.
Do thicker or thinner wires have more Resistance?
Over the same distance the larger diameter wire will have less resistance that the smaller diameter wire.
A decrease in the diameter of a blood vessel is termed?
vasoconstriction.
How do you decrease he size of a circle?
By reducing its radius or diameter.
How does the resistance of a wire vary with its diameter?
At a greater diameter, the cross-section will also be greater, and therefore the resistance will be less. This assumes that other things are equal, of course.
