Physics investigation: aishwarya moothan (2013) conclusion after thorough analysis of the data collected and the graphs derived from data it is seen that the resistance in the wire with the cross sectional area of 0001 (w1) was greater than that in the wire with cross sectional area of 0004 (w2), thus proving my hypothesis correct. An investigation into the resistance of a wire - gcse an investigation into the resistance of a wirefree gcse physics coursework essayresistance of a wire - physics coursework gcse - gcse physics coursework - resistance plan what affects the resistance of a piece of wirethere are many variables in this investigation the resistance of the wirefree resistance of wire essays and papers. Some useful worksheets for the old resistance in a wire coursework. 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 you must use thick wire to carry a large current, or the wire gets too hot and melts (like a fuse) the relationship between resistance and thickness is.
The resistance r is the resistance wire (constantan nichrorome) that you will be trying to calculate set the power supply to 1v this limits the current through the wire in order to reduce any heating effect which may change the resistivity. Mr habgood shows you how to measure the resistance of a wire when you change its length. Resistance in a wire gcse science marked by teacherscom 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.
Length of wire and resistance coursework an investigation into the resistance of a wire - hubpages free gcse physics coursework essays an investigation into the resistance of a wire noticed that if you double the length of the wire , the resistance is roughly.

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 measure of how easy it is for current to flow through a wire current is the rate. 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 things that affect the resistance in a wire are:.
Gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire. For the resistance of a wire coursework, i have already done it based on experimenting with different lenghts against resistance for the evaluation, i need to write an extension on the coursework: i have a few ideas already • experimenting with other types of materials of wires to see if they. I am currently doing my physics coursework and i was just wondering if you could help me get a bit more scientific information on why things occured and happened the way they did basically i am studying how length affects the resistance of a wire and i have initially completed this project but i am just re-reading and adding in some information. Data analysis: resistance of a wire data analysis the investigation i did was to find the resistance of a piece if wire the piece of wire is my dependent variable throughout the investigation i changed the length of the wire in order to measure the resistance of each length plan in this investigation, a simple circuit will be set up to. So when you have resistors in series like this, the total resistance, their combined resistance, is just equal to their sum and that was just a very long-winded way of explaining something very simple, and i'll do an example.
This course explains how to analyze circuits that have direct current (dc) current or voltage sources a dc source is one that is constant circuits with resistors, capacitors, and inductors are covered, both analytically and experimentally. Theoretical analysis on ac resistance of copper clad aluminum wires kenichiro yashiro, 1 2chihiro kamidaki, 4takashi shinmoto,3 and ning guan wireless power transfer system using inductive coupling through magnetic field requires low wire model for analysis. The resistance of a wire depends on the number of collisions the electrons have with the atoms of the material , so if there is a larger number of atoms there will be a larger number of collisions which will increase the resistance of the wire. 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.
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 things that affect the resistance in a wire are. If the resistance of the wire is high and the current is large, the wire may get red hot conductors which provide a high resistance are called resistors this can be linked to the ohm’s law. Physics experiments (electricity) ‘in the matter of physics, the first lessons should contain to investigate the variation of the resistance of a metallic conductor with temperature 8 of the leads plus the resistance of wire between the crocodile clips from the ohmmeter. Introduction to short circuit analysis course content a short circuit is a low-resistance connection established by accident or intention between two points in an.
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 current through it, will effect its resistance. 3 students should come to understand that the resistance of a wire depends on its length, its cross sectional area, and the material out of which it is made with some students you could go further and introduce the concept of resistivity ρ, through the relationship r = ρ l / a where r = resistance, ρ = resistivity, l = length and a = cross. Join now to read essay physics coursework theory - resistance of a wire theory behind my experiment thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire.
Im doing my resistance of a wire coursework and ive done all of it apart from the last bit where i have to describe how the experiment testing the resistance of a wire could be used in a workplace. Modern technology is that there's a lot of wire, you know, putting those 10 million gates together, you know, 10, 20 million wires you know, kilometers and kilometers of wire around the surface of the chip.
