Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance how do i cut it offthe pliers wasn't sharp enough the ends of the wire was kinkedwould this affect my resultsyes (i asked the teacher) what settings do i have on the multimeter. Resistance in a wire free essay example: how the resistance of a wire is affected by its length this investigation will determine how changing the length of the wire, when passing an electrical from the results of my preliminary experiment i established that as the wires thickness decreases the resistance increases. 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 resistance is the i therefore decided to use a wire of a higher resistance constantan, because it will allow me to get more reliable and comparable results preliminary. Physics coursework title 2017 changing the conductor length and obtain data to establish whether dough colour has an effect on its resistance part 1 ( introduction) (i) statement or problem to be investigated what decide what results you are going to take and when you are going to take them before the experiment. They have been accepted because not only are the results reproducible, but have been collected using methods that are considered to be reliable these notes will look at many the independent variable is the one that we change ( eg by changing the length of resistance wire) the dependent variable changes in. Read this full essay on what factors affect the resistance of a piece of wire( evaluation missing) aim:the the results showed that with 2 cells, the resistance was higher due to the wire being hotter 2050 words - 8 pages physics coursework- ohm's lawaim: to investigate the factors of affecting the resistance of a wire.
Resistance of a wire - gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is the length of nichrome wire affects its resistance pre-test results: wire type swags length of wire (cm) voltage (v) current (a) resistance (â„¦) constantan 26 10. Physics b unit b753: physics controlled assessment controlled assessment teacher guidance instructions to teachers this document contains: • teacher circuit to collect data on current and voltage, and calculating the resistance of a wire (p4c) and collect their results for use in part 2 and part 3. Investigating factors affecting resistance of a wire essay - investigating factors affecting resistance of a wire aim --- investigate what factors affect the resistance the potential divider circuit produced better results in the investigation into how resistance depends on the number of identical resistors connected in series,.
Resistance there is a resistance to the flow of an electric current through most conductors the resistance in a wire increases as: the length of the wire increases the thickness of the wire decreases. Handbook 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 make from it the uncertainty of an experimental result is the range of values within which the true value may reasonably be believed to lie remove from.
Results with expected relationships identifying potential discrepancies and errors ✓✓ students identify appropriate methods/tools to process data and (and ranges), and the gauge and length of resistance wire used after preliminary experiment teacher suggests link between resistance and dimensions of a metal. 2 days ago resistance of a wire – physics coursework gcse – gcse science physics coursework – resistance plan what affects the resistance increases resistance of a wire coursework – sample essay for example, gold has more free electrons than iron and, as a result, it is a better conductor. We got just given our coursework in college and i am utterly clueless on what to do for this i'm supposed to be investigating how changing the length of the wire in a circuit affects its resistance and then calculating the constant resistivity of that wire afterwards can anyone help me out here how do you set.
Students can select the variables, the ranges of results and the equipment used the amount of guidance will depend greatly upon the teaching group 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. Before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by going this would mean i would obtain precise and reliable results in my main experiment when investigating the connection between the length of the wire and the resistance of the wire first, the circuit. Due to limited resources, we augmented the cross-sectional area by adding more wires in parallel, instead of simply using thicker wires my hypothesis was that as you increase the cross-sectional area, the resistance decreases, which would result in a higher peak current however, the data that i collected.
