The four factors that affect the resistnce of a wire are: 1 length of wire 2 thickness of wire 3 temperature 4 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. Learn about the physics of resistance in a wire change its resistivity, length, and area to see how they affect the wire's resistance. There are different variables that can be changed in this experiment these are the independent variable however, due to my line of enquiry, i will only change the length of the wire the variables i will control will be the type of wire (resistivity ) and the cross-sectional area of the wire i will also control, using. Not associated with the experiment were kept away (a risk assessment was the alligator clips were clipped together, so that the resistance of the wires of the 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. Turn the dasi box upside-down and locate the four—wire resistor used in it: hat terminalso'n the top of the box are wired to, the resistors current lead/s2 the thin wires connected - ( m'mmwwmﬂwm / to the resistors voltage give the predicted formula for the relationship between r and l under study in this experiment. How the length of a wire affects its resistancein my physics coursework i am going to investigate the effect of the length of a wire on its resistance i predict that as the length of the wire increases, the resistance of the wire will also increase, because there will be more ions and electrons for the free electrons to collide with.

The resistance of a wire investigation - the resistance of a wire investigation the aim of this experiment to find the relationship between length of wire and the resistance it will create variable: here are the list of variables in this investigationâ€¦ control variables: â voltage of circuit â type of wire â thickness / cross. The resistance of a wire is directly proportional to the length of the wire and inversely proportional to the resistance, which is what i predicted it is also your results, the method you used and how well you managed the risks the wires did not get hot and nothing broke so we did the experiment safely. In this piece of coursework you have to take careful measurements, with particular attention to the quality of the measurement and any inferences you can is it to measure a particular quantity (eg young' modulus), to establish a mathematical relationship between two variables (eg resistance and temperature of wire),.

The key variablength/resistance of a wire- brief how is resistance of a wire affected by the length of a wire han experiment to find the resistivity of nichrome- a planning plan of the method to be used: - the resistivity of nich physics investigation - resistance of wire- aim: - to find out what factors affect the resistance. But note: if the current is too large, the voltage of the cells will fall due to their internal resistance for this reason, it is important to keep the current very low - copper wire is effectively a short 5 how science works extension: this experiment can be used as a more open-ended investigation students can select the variables,.

- The resistance of a conductor is a measure of how easy or hard it is for a current to flow through it a wire will warm up when a current flows through it an increase in temperature will increase the resistance of the wire so measurements have to be taken quickly before the wire has a chance to warm up.
- Wire(s) other details of experiment fully specified teacher suggests outline method to determine resistivity by measuring resistance of wire but does not provide a circuit diagram students decide on instruments (and ranges), and the gauge and length of resistance wire used after preliminary experiment teacher suggests.
- Circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) teachers may wish to in their investigations, candidates will need to make choices about: the variables to be measured the teachers are advised to try out the experiment prior to candidates undertaking the task marking the.
- Before starting my coursework i have decided to choose 2 factors that will affect the resistance of a wire i will do this by going from my graph i have shown that my prediction was correct, as the line of best fit is a straight line proving that the resistance of the wire is proportional to the length of the wire the length of the.

I found out from my science teacher that a metallic conductor is a wire, for example, copper wire investigation is stated as a problem statement during the investigation i intend to answer the following question “how does the length of a wire affect it's resistance” preparation & planning identification of variables. Aim of the experiment the aim of this experiment is to investigate how temperature impacts the conductivity and resistance of a conductor using a copper wire, this experiment will try to analyse if the flow of electric current through the wire is affected by varying the temperature of the wire at the conclusion of the experiment.
