Does the diameter of the wire affect the resistance ohms law states that if the cross section of the wire is uniform then the resistance is proportional to the length and inversely proportional to the area of the cross section the diameter of the wire will have an affect on the resistance of a wire. How does length affect resistance and resistivity instructor preparation and discussion developed by: angela jones, phd 1, 2 1 does the measured resistance vary with the length of the line 2 does the calculated resistivity vary with the length of the line 3 (optional) draw another line twice as wide – does the measured. The longer the wire, the more electrons have to be pushed against the resistance of the wire to push an electron out the other end, thus the higher the resistance of the wire in answer to other questions you've posed in comments. Originally answered: how does the resistance of a wire depend on its length there is a formula which defines the resistance (r) of a wire which is defined r = pl/a “p” is the specific resistance of the wire material, “l “is the length of wire and “ a” area of cross section of wire.
Type of metal aim: to investigate how the length of a nichrome wire can affect the resistance of a wire prediction: in my opinion the longer the wire the more resistance there will be i believe this because if the length of the wire is increased then the resistance will also increase, as the. - investigating how the length of the wire affects the resistance of the current passing through wire aim for this experiment, my aim is to investigate how the length of the wire affects the resistance of the current passing through the wire. For example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double in my main investigation i will see if this observation applies to my results.
- resistance of a wire planning: i am going to design an experiment to measure how the length of the wire affect the resistance in the wire i will use the same wire for all my measurements it is important to have a fair test, so the cross-sectional area of the wire must be the same for all measurements because as the cross-sectional area. 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 experimentally, the dependence upon these properties is a straightforward one for a wide range of conditions, and the resistance of a wire can be. The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance there are factors which can affect how accurate our expriment is come on four levels.
How the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire current is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter. Observe changes to the equation and wire as you play with the resistivity, length, and area sliders sample learning goals predict how changing each variable will affect the resistance. 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.
This first report in physics will show the investigation of how the length of a wire affects its resistance for starters i will go through the main definitions, to get a better knowledge of what is going to happen. 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 length of a wire affect resistance because if a long wire is used in an electrical connectionthe resistance to be used in driving current round the circuit will be used in overcoming.
Rdc - commonly referred to dcr which is the series resistance of a cable at zero frequency rac - the resistive portion of the cables series resistance as a function of frequency due to skin effect rs - total series resistance (mohms) measured tip to tip at one end of the cable while the other end is shorted. 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. Circuit wiring table of contents so long as a complete circuit is formed does the wire length or circuit “shape” matter to our calculations as such, they contribute no appreciable effect to the overall resistance of the circuit, and so the only resistance we have to contend with is the resistance in the components in the above.
L is the length of the wire, a is the cross-sectional area of the wire, and r is theresistivity of the material long, thin wires have the most resistance,just like long, thin pipes long, thin wires have the most resistance,just like long, thin pipes. The resistance of a typical conducting wire is low when temperature is low and high when temperature is high the increase in resistance alongside temperature is due to an increase in energy of the wire atoms, which cause them to vibrate more and impede the path of the electrons flowing through a. First, the total length of the wires will affect the amount of resistance the longer the wire, the more resistance that there will be there is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse.
