– nichrome wire conducts electricity very well and because current is the movement of atoms through the wire, if the wires length is doubled so is the number of electrons which will double the resistance. The connection between current, voltage and resistance was discovered in 1827 by georg ohm, a german physics and maths teacher the formula v = i × r is known as ohm’s law it was such an how does length affect resistance when the length of the wire increases, resistance increases. 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 fact that, as the wire got shorter and therefore the resistance greater, i could not keep the wire from heating up 2 the wire i was using had a tendency to wind up, diminishing my precision and accuracy in measuring the length.
- investigating resistance of a wire aim: to investigate how the resistance of a piece of resistance wire depends on length and to find the length of wire needed to make the required resistance prediction: i predict that when you increase the length of the resistance wire the resistance will increase. Physics gcse coursework: resistance of wire aim: to investigate if the length of wire affects its resistance prediction (hypothesis): i predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistance. The resistance of a wire is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire (3) this means that when the disconnect the wire and use a metre rule to make the length of wire between the clips 60cm 4 repeat step 2 5 put 30cm of wire between the clips and repeat step 2. 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.

Gcse physics coursework - resistance of a wire courseworkresistance of a wiretaskto investigate how the resistance of a wire is affected by the length of images for gcse physics coursework resistance wire gcse physics coursework resistance wire conclusion. The relationship between resistance and the length of the wire is directly proportional this means that the greater the length of a wire the larger the resistance my chosen variable: the variable i have decided to use is the length of wire because i believe that it is the easiest to control to my ability. The wire will always be constantan (28swg) my prediction is that as the length of the wire increases so will the resistance i have decided this because the electrons have to travel further when the wire is longer and more atoms get in the way of electrons travelling and therefore the resistance of the wire is higher. Average the resistivity and resistance values and record these values on your data sheet v:f06 did the resistance vary signiﬂcantly with length (length here is the distance between the top nails) resistance of the wire, the voltage drop across the wire, and the current passing through the wire explain your reasoning.
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. The resistance is calculated by resistance-p d across the wire/current through the wire (1) i conclude that as the length of a wire doubles, the resistance also doubles (provided the thickness of the wire is kept constant0. 首页 论坛 时尚 science resistance coursework – 664436 该话题包含 0 回复，有 1 参与者，并且由 rowebipate 于 9 月， 2 周 前 最后一次更新。 正在查看. The resistance in the wire increases as the length of wire increases my results do show that my hypothesis was correct this is because in the preliminary experiment the thinnest wire gave us the widest range of resistance, as i predicted in my hypothesis.
An investigation into the resistance of a wire free gcse physics coursework essay show that as the length of the wire increases, the resistance increases, as well furthermore, if you double the length of the wire, the resistance is roughly doubled for example, when the length of the wire is 20cm the resistance is 314 ohms when the. If the length of an electrical conductor increases, then the conductor’s resistance will increase, if the cross-sectional area increases, then the resistance will increase because resistance occurs due to charge carriers and the atoms of the wire colliding, longer wire, more collisions. Resistance of a wire task the resistance of a wire depends on factors, one of which is the length of the constanton wire, i will be investigating this into more detail.
Resistance of a conductor will decrease if its length and temperature remain constant method wire lengths (independent variable) of 20 cm, 40 cm, 60 cm and 80 cm were used. Unit length of wire quantitative treatment provided of spread of data and thus level of uncertainty calculating cross sectional area of wire from the diameter graph drawn with correct scales and accurate plotting to show relationship between resistance and cross sectional area.
