When electrons start to move, they get scattered from the nuclei present in the material which is the wire made from this process creates the resistance thus, when the length of the wire increases, the amount of particles scattered from the nuclei increases which also increases the resistance. Any material that affects conductivity will be a good resisting factor to the flow of electricity how does the resistance of a conductor vary if the length of a . How does the change in the dimension of a material affect the resistivity of that material how is the resistance of a wire affected if its length is doubled what factors can lower the electrical resistance of a wire. The resistance of a wire depends on 3 parameters: the conductivity of the material from which the wire is made, its cross sectional area, and its length highly conductive materials, such as copper and silver, are used to manufacture wire to achieve a low resistance. How does increased conductivity affect voltage tags: ohm's law or does resistance decrease mr davis 97, feb they are properties of materials and not of the .
How do different materials affect resistance conclusion my conclusion was that the handkerchief parachute can float for the longest by joshua shadood 7th grade. Which of the following does not affect the electrical resistance of a body a temperature of the body b length of the body c material composing the body. When does the air resistance force make a difference rhett allain the material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior .
Which of the following does not affect a material's resistance ohm's law which of the following wires would have the least resistance, assuming that all of the wires have the same. Factors that affect resistance of a wire a third variable which is known to effect the resistance to charge flow is the material that a wire is made . There are many variables that could affect the resistance of the piece of wire: length potential difference tension temperature diameter shape material of the wire i have chosen to do length because i think this will give me the biggest range of results. Materials that become superconducting at higher and higher temperatures at the present time, how does temperature affect electrical resistance assessment type:.
Best answer: a third variable that is known to affect the resistance to charge flow is the material that a wire is made of not all materials are created equal in terms of their conductive ability. To remove the effect of size from resistance, resistivity is used - this is a material property which does not depend on size restivity is affected by temperature - for most materials the resistivity increases with temperature. A third variable that is known to affect the resistance to charge flow is the material that a wire is made of not all materials are created equal in terms of their conductive ability some materials are better conductors than others and offer less resistance to the flow of charge. An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or r-value -- the higher the r-value, the greater the insulating effectiveness the r-value depends on the type of insulation, its thickness, and its density.
Effect of temperature on resistance but when the temperature increases so the resistance of the material decreases these materials are used in the circuit for . Resistance, or impedance, decreases electrical current per ohm's law ohm's law gives current as a ratio of voltage to resistance: 1 volt flowing through 1 ohm of resistance produces 1 ampere of current resistance is the property of an object, and resistivity is the property of the substance of . For this experiment, the factors which will be tested and measured will be the length of the wire, the material of which the wire is made from to see whether it affects the resistance, and seeing whether the variable resistor also affe. How are the resistance of a conductor and frequency of an ac current related if frequency goes up, does resistance go down or vice versa is this relationship constant for all types of material are some materials more frequency sensitive than others for instance in an incandescent light, if we .
In the air resistance formula (f=1/2rhov^2c_da) the higher the velocity the more air resistance there will be for an object how does air resistance affect the . Q & a: things affecting resistance what can effect the resistance if a resistence wire and are ther different types of resistance wires materials may also . First i will need to identify the factors that effect resistance the possible variables i could use to find out factors affecting resistance are material wire is .
How does material affect resistance how does the diameter of wire affect the resistance in a circuit introduction: some metals such as copper, silver and gold are very good conductors of electricity. Resistivity and laws of resistance that means resistance of a material of unit length the temperature of the substance also affects the resistance offered by . Resistance of a conductor tells us how easily a conductor allows the flow of current through it material al/cu: class of conductor: transmission effect .
