There are four factors which influence the amount of resistance of a conductor: type of material, length, thickness and temperature different materials will offer different amounts of resistance longer length resistors will offer more resistance than shorter resistors. Investigating the effect of length on resistance is common but some students may wish to investigate the effect of the thickness of wire in either case, different wires should be made of the same material. The kind of material being used in thermal conductivity can affect the rate of energy flowing between the two regions the greater the conductivity of the material, the faster the energy flows according to the physics hypertextbook, the material with the greatest conductivity is helium ii, a superfluid form of liquid helium, which exists only. To help me plan my investigation i have completed a preliminary experiment in which i investigated the effect of the thickness of a wire on its resistance, using three constantan wires and one copper wire.
This experiment was a fair test because other factors that could affect the resistance in a wire were kept constant such as length, material of wire and temperature of wire the equipment used for experiment was also kept constant, as was the environment for the experiment. The main factors that affect the resistance in a conductor are: length temperature cross sectional area material magnetism the factor that we are going to change is the cross sectional area hypothesis: i think that the higher the cross sectional area, the lower the resistance in the conductor will be.
The four properties of the string that affect its frequency are length, diameter, tension, and density these properties are described below: when the length of a string is changed, it will vibrate with a different frequency. Recommended: a paper towel holder, or materials to make a simple spool holder for the magnet wire, like a pencil and a small cardboard box recommended project supplies get the right supplies — selected and tested to work with this project. Resistance and thickness of wire (cross-sectional area) compare two circuits with batteries of the same voltage, with the same length of wire, made of the same material, but one wire is thicker than the other.
By steven holzner conduction transfers heat through material directly, through contact thanks to physics, we know that conduction is affected by temperature difference, the area of conduction, the distance the heat must travel, and the amount of time that passes. Electricity the resistance of wires-thickness does the resistance of a wire depend on its thickness the resistance of a wire changes if its thickness changes the thinner the wire, the bigger its resistance. Resistance in a wire coursework 1540 words | 7 pages 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 the resistance. The length of the neutral axis is calculated as a bend allowance, taken at 50 percent of the material thickness in machinery's handbook, the k-factor for mild cold-rolled steel with 60,000-psi tensile strength is 0446 inch.
The wire material is also an important factor to consider, as it can affect the wire length that can be used on a project highly conductive materials like silver and copper offer the least amount of resistance to the flow of electrons compared to a highly resistant material like rubber. Data collection, processing, representation and analysis measurements of the wire o table 03: measurements of the wire a: 20cm specification wire a area 01256×10-8 square millimetre length of the wire 20cm material copper o table 04: measurements of the wire b: 40cm specification wire b area 01256×10-8 square millimetre length of the 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.
- an investigation to discover factors that can affect the resistance of a wire aim i shall be investigating factors that can affect the resistance of a wire the possible variables i could choose are length, thickness, type of metal, shape, temperature and density of metal. Any conducting wire has a resistance associated with it and the resistivity of the material is directly proportional to the length of the wire and inversely proportional to the area of the cross section of the wire although doesn't have a greater impact, they do affect the voltage across it and thereby the current.
