If you plot a graph of resistance (y axis) against length of wire (x axis), how do you find the resistivity using the graph note: the cross sectional area is constant thanks. An investigation into the resistance of a wire - gcse physics 30 dec 2016 an investigation into the resistance of a wirefree gcse physics coursework essayresistance in a wire - gcse science - marked by teacherscom free essay example: the diameter of the wire will have an affect on the resistance of a wire. Investigating resistivity the event be defined as the wire length modify the graph to display resistance vs length between resistance and length of the .
Awg - american wire gauge see our other electronics calculators the awg is a logarithmic scale, so given an know resistance or diameter for a certain gauge, you can quickly figure out the resistance and diameter of another gauge number, by addition and subtraction. Resistance in a wire free essay example: how the resistance of a wire is affected by its length this graph shows the resistance in a 34 swg constantine wire it . Nevertheless when the values of graph 13 are compared to those of graph 12 , the (i) values of graph 13 are greater, indicating that the resistance of in this graph, and thereby w2 was lesser.
The resistance of a wire is given by the equation: r = ρ x l/a where r is resistance, ρ (pronounced 'rho') is the resistivity of the wire, l is length and a is its cross-sectional area the gradient of each graph will give you the quantity ρ /a. Graph, the lower the resistance of the wire the connection between current, voltage and resistance was discovered in 1827 by georg ohm, a german physics and. Resistance of a wire conclusion hi, i am currently doing my physics coursework, and i need your help on what to write for my conclusion what do i need to .
Factors that affect the resistance of a wire the resistance of an object is a measure of the how reluctant current is to flow through that object it is given the symbol r and has the unit w (which is a greek letter omega and pronounced 'ohm'). An investigation into the resistance of a wire free gcse physics coursework essay this was because i could plot a graph and show the general trend. Resistance in a wire coursework in this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease . 3 students should come to understand that the resistance of a wire depends on its length, its cross sectional area, and the material out of which it is made with .
I did an experiment to investigate how current varied with changing resistance and plotted my results on a graph of 1/current against resistancethe graph is a straight line showing $1/i$ to be dir.
