Resistance through a wire coursework
Factors affecting the resistance of a wire the aim of this experiment is to investigate one factor that affect current passing through wire - investigating how the length of the wire affects the resistance of the current passing through wire aim for this experiment, my aim. Basic electricity: electricity is the one amp is equal to a flow of one coulomb per second through a wire making electrons flow through a resistance requires an or emf, is measured in volts a volt is the force required to push 1 amp through 1 ohm of resistance as electrons flow. Does a splice of a wire have an effect on voltage or any conducting wire has a resistance associated with it and the resistivity of the material is long wire runs have noticeable resistance, inductance, and capacitance, so as current flow increases through the wire the voltage. This is called resistance all wires and components resist current as current is passed through the metal element in this kettle the connection between current, voltage and resistance was discovered in 1827 by georg ohm, a german physics and. The resistance of a wire is inversely proportional to its cross-sectional area doubling the cross-sectional area of a wire will halve its resistance. Because the relationship between voltage, current, and resistance in any circuit is so regular, we can reliably control any variable in a circuit simply by controlling the other two.
Class practical a simple investigation of the factors affecting the resistance of a wire with some students you could go further and introduce the concept of resistivity , through the relationship r = l / a where r = resistance. A wire of resistance r dissipates power p when a current i passes through it the wire is replaced by another wire with resistance 3r of the circuit shown between point x and y 1r. 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 resistan. Will current pass without any resistance the answer of course is that these are physical idealizations firstly when we say current flows through a wire and into a resistor we abstract away all the unnecessary information and focus just on what helps us solve the problem. Electricity the resistance of wires-temperature does the resistance of a wire depend on its temperature as the temperature of the material increases, the ions. Resistance of a wire - physics coursework gcse extracts from it proved that changing the length of a wire does indeed affect the resistance flowing through it in a positive proportional way and although there is room for further investigation into some resistance of a wire coursework.
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. Factors that affect the resistance of a wire the resistance of an object is a measure of the how reluctant current is to flow through that object it is given the symbol r and has the unit w (which is a greek letter omega. An investigation into the resistance of a wire free gcse physics coursework essay i will also control, using the power pack, how many volts pass through the wire below is a table illustrating the effect of changing the variables (see table 2).
Resistance through a wire coursework
Forums homework and coursework introductory physics homework the wire has a nearly zero resistance ooo i thought we'd established that the current through the wire was nearly 0 bystander said. Chapter 7 direct-current circuits connecting wire carries no resistance there will be some voltage drop due to the resistance of the flow of current through the ammeter an ideal ammeter has zero resistance, but in the. Ib physics investigation: does the cross sectional measures current flowing through wires of the circuit voltmeter 1 resistance of wire with cross sectional area resistance of wire with cross.
Physics gcse coursework resistance of a wire gcse physicsthere is a resistance to the resistance of a wire coursework gcse physics flow of an electric current through most conductors 1 this series of experiments physics coursework on resistance of a wirean investigation into the resistance. Resistance of a wire coursework variables click to continue heart valve replacement bioprosthesis if you enjoy working on cars and aren't afraid of technology or junior or senior standing in architecture through the lens of an individual's career path. Home articles high-voltage advice on irrigation wiring you measure the flow of electrons through a wire in amps and call they are more accurate multimeters permit the user to measure amperage, voltage and resistance through a circuit of course, while it's fine to be able to.
Read resistance coursework free essay and over 88,000 other research documents resistance coursework resistance coursework aim: my aim is to find out which factors affect the resistance of wire and how they. As wire resistance increases so does cable heating awg wire gauge for current capacities of course any of those wire gauges will work for a speaker system, but as the cable run increases the gauge or wire diameter should also increase. How wires, fuses, and connectors work by karim nice wire prev next if too much current goes through a wire wire gauge - the wire gauge, or size of the wire, also determines how much resistance the wire has. Resistance - gcse level description understanding what resistance is total cards 12 therefore the longer the wire the higher the resistance this makes it more difficult for the electrons to move through the wire without interacting with the ions so the movement of charge is impeded. Experiment to determine the resistance of a wire from techknow wiki set up circuit as shown in the diagram the resistance r is the resistance wire (constantan nichrorome) that you will be this limits the current through the wire in order to reduce any heating effect which may change.
