What will be the effect on resistance when wire Get tripled itself?
When a wire tripled itself its length is 1/3 rd and area becomes tripled and area is inversely proportional to resistance.
How does the resistance of a wire change when its diameter is doubled?
From this relation we can conclude that resistance is inversely proportional to area A of the conductor. Area of the conductor becomes 4 times the area of the conductor without doubling the diameter. Thus, we can say that new resistance will decrease four times.
How does the resistance of a wire change when its material is changed to one whose resistivity is 3 times?
c) it’s material is changed to one whose resistivity is three times thats it the resistance will decrease nine times of initial.
How does resistance change with radius?
For example, a 2-fold increase in radius decreases resistance by 16-fold! Therefore, vessel resistance is exquisitely sensitive to changes in radius. The relationship between flow and vessel radius to the fourth power (assuming constant ΔP, L, η and laminar flow conditions) is illustrated in the figure to the right.
How will the resistance and resistivity of a conductor change when its length is tripled by stretching it?
Resistivity of a conductor such as wire will increase by nine times when it is stretched by three times. It is directly proportional to the length and inversely proportional to diameter. So the resistivity will also triple.
What happens to resistance when a wire is stretched?
When the wire is stretched to double the length , the area of cross section gets reduced to half. So when the wire is stretched, the resistance multiplies by four times.
How does the resistance of a wire change when diameter is halved?
Resistance is inversely proportional to the cross-sectional area. So if the diameter is halved the cross-sectional area is quartered and the resistance is quadrupled.
How much does the resistance of a wire changes if its diameter?
So the wire resistance is inversely proportional to diameter or cross sectional area. this means when the diameter of the wire is doubled, the resistance will be 1/4 of the original value due to R is inversely proportional to π(d/2)².
How does the resistance and resistivity change if area is change?
Resistance is proportional to resistivity and length, and inversely proportional to cross sectional area.
How does the resistance of a wire vary with its?
Electrical resistance is directly proportional to the length (L) of the conductor and inversely proportional to the cross-sectional area (A). Resistance is inversely proportional to the area of cross-section. When the area of cross-section increases the resistance decreases and vice versa.
How does radius affect pressure?
The more viscous a fluid, the greater the pressure gradient required to cause it to move through a given tube. Because the resistance of the flow is inversely proportional to the fourth power of the radius, small decreases in the radius of a tube cause profound decreases in the flow of the fluid through the tube.
How does resistance and specific resistance of A wire depends on its length and radius?
Resistance is directly proportional to the length and inversely proportional to the square of radius. Specific resistance is independent on the dimensions of a wire.
How does the resistance of a wire change when its diameter is tripled?
How Does the Resistance of a Wire Change When: Its Diameter is Tripled? – Science How does the resistance of a wire change when: its diameter is tripled? Thus, the area of cross-section will become nine times. Thus, the resistance will be reduced by nine times.
How does radius affect the length of a wire?
Since the radius is tripled so area ‘A’ increases to ‘9A’ thus reducing the resistance of the wire by 9 times. This also effects the length of the wire. Since the volume is constant and assuming the wire is cylindrical : initial volume = final volume
What happens when you double the length of a conductor?
If you double the length of the conductor by rolling more off the drum, l will double but other values on the right-hand side of the equation will stay the same. So the resistance R will double. If you double the length by cutting off a length and then s-t-r-e-t-c-h-i-n-g it out to double its initial length, you would expect the con
