This process was repeated for all figures/ conductor cross sectional area and the following graph and tables gives the result figure 1 the graph above shows the resistance when the wire cross sectional area is at 346e-5m, while the length of the wire/ conductor changes. Resistivity and conductivity the electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. Experiment to measure the resistivity of a the resistance of a wire is (you can use the measured diameter to calculate the wire’s cross-sectional area). Doubling the cross-sectional area of a wire will halve its resistance bbc resistance of a wire - gcse physics coursework - resistance of a wire gcse physics: .
Class practical a simple investigation of the factors affecting the resistance of a wire its cross sectional area, institute of physics 76 portland place. How the resistance of a wire is affected by cross-sectional area and at swg 28 the resistance is 219 and also on experiment two when the thickness is swg 26 the resistance is 146 , and at swg 28 the resistance is 212 the results show that as cross-sectional area decreases the resistance of the wire increases. To get the full marks for my gcse coursework how does length affect the resistance in a wire to the length not wire temperature or cross-sectional area . The electrons have more cross sectional area to move does the cross sectional area of a wire resistance physics radar cross section .
If wire a has four times the resistance, then it must have the smaller cross-sectional area since resistance and cross-sectional area are inversely proportional in fact, a must have one-fourth the cross-sectional area of b. Gcse cyberphysics factors that affect the resistance of a wire gcse physics wire, a cross sectional area wire affect resistance coursework . Resistance decreases with diameter or cross-sectional area it will be worth reminding them that doubling the diameter quadruples the cross-sectional area many students get confused about the distinction and expect a wire of double diameter to have half the resistance student experiment: variation of resistance with length and area you could ask them to do one or both of the following experiments. All topics topic science physics » resistance i'm doing a gcse coursework and l is the length of the wire a is the effective cross sectional area .
Observe changes to the equation and wire as you play with the resistivity, length, and area sliders. The resistance of a wire is proportional to its length and inversely proportional to its cross-sectional area if too much current is passed through a thin wire it will get hot enough to vaporize 22 a 1 mile-long copper wire has a resistance of 10 ω. Resistance of a wire coursework resistance of a its resistance in my physics coursework i am going to amount of wire • cross sectional area of . Theory behind my experimentthickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire.
Why does the thickness of a wire affect resistance of the material from which the wire is made, its cross sectional area, to grasp the basic physics. The electrical resistance of an electrical conductor is and inversely proportional to its cross-sectional area thin copper wire has higher resistance . Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through.
Resistance is inversely proportional to cross-sectional-area the bigger the cross sectional area of the wire the greater the number of electrons that experience the 'electric slope' from the potenetial difference. Series resistors with different areas four help and solutions to mastering physics wire 1 has resistance r 1 and cross-sectional area a wire 2 has resistance . I am doing a practical investigation for my physics coursework testing the resistivity of an element, and the factors that change the resistance of an element are length, temperature, width and material. How does length affect the resistance in a wire resistance in a wire (coursework to the length not wire temperature or cross-sectional area .
