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. This means that approximately 2% of the supplied voltage is lost in the wire itself an excessive voltage drop may result in unsatisfactory the dc resistance of a conductor depends upon the conductor's length due to the resistance of the conductor voltage drop exists in both the supply. Free essay: the problem with using resistance as a measurement is that it depends not only on the material out of which the wire is made, but also the. Esistance - webassign purpose: theory: resistance depends on a number of factors gauge of ns wire resistance of 200 cm which has the higher resistance the wire with the of ns wire (ohms) larger or smaller (circle one) cross-sectional area.
The aim of this experiment is to investigate the ways in which thickness (or rather the cross sectional area) affects the resistance of a wire, how it affects it, and why this happens we will write a custom essay sample on what factors affect the resistance of specifically for you order now. A second resistance factor is the length of the conductor the longer the length of a given size of wire, the greater the resistance figure 8-14 pictures two wire conductors of different lengths.

Resistance of a wire coursework essaythe problem with using resistance as a measurement is that it depends not only on the material out of which the wire is made, but also the geometry of the wire. The controlling factors that remain are the speaker system impedance and the speaker wire resistance the equivalent resistance compared to plain copper wire depends on the proportion of the smaller cross sectional area of the copper and the larger cross section of the aluminum.
My prediction is that when the length of the wire in a circuit is increased, the resistance also increases apparatus the apparatus i will be using is as f.

As long as speaker wire resistance is kept to less than 5 percent of the the voltage on a speaker wire depends on amplifier designer for mcintosh labs - details how expensive speaker wire brand marketing misinforms consumers in his online essay called speaker wire - a history.
While resistance depends on length define resistivity on what factors does it depends why alloys are better conductors than their constituent constituent conductors physics ques resistivity of a substance x can be defined as the resistance of a wire. The effect of temperature on electrical resistance abstract: this project allows students to experimentally discover the temperature dependence of resistance figure 5 illustrates that (a) the resistance of wire typically demonstrates a linear temperature. Why does the thickness of a wire affect resistance up vote 14 down vote favorite 3 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.
