The resistance of a wire depends on 3 parameters: the conductivity of the material from which the wire is made, its cross sectional area, and its length highly conductive materials, such as copper and silver, are used to manufacture wire to achieve a low resistance. In this investigation i intend to research how the length of a wire affects its resistance when connected to an electric circuit predictions my prediction is that the greater the length of the wire, the greater the resistance. The higher the temperature of a conductor, the higher its resistance due to the high values of potential difference and current if a thin wire in a lamp tends to resist the movement of electrons in it, then we say that the wire has a certain resistance to the current.
The resistance of a wire will prevent the amount of electric current from flowing through the wire (conductor) maximally the lower the resistance of a wire, the more the amount of electric current can flow through the wire and the higher the res. How the length of wire affects its resistance - sample essay introduction- in our investigation we are trying to find out that what are the factors which effect the resistance of a resistance wire through textbooks and information from the internet i have identified these factors. Introduction in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire there are many things that affect the resistance of a wire but i have only got the chance to do one of these.
Resistance depends on the material the wire is made of the more tightly an atom holds on to its outermost electrons the harder it will be to make a current flow the more tightly an atom holds on to its outermost electrons the harder it will be to make a current flow. Essay sample the objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance there are factors which can affect how accurate our expriment is come on four levels. It alters its inductance, which effects its inductive reactance, which effects its impedance, which is a measure of resistance to alternating current (ac) flow impedance = resistance + reactance inductive & capacitive reactance is frequency dependant. To detect how resistance affects current, i must first discover what factors affect resistance these factors are: length of the wire - if a wire is longer there are more particles for electrons to move through, and therefore more resistance. Investigating how the length of wire affects resistance essays these are sample investigating how the length of wire affects resistance essays contributed by students around the world.
This experiment was regarding electricity and its features the experiment determines factors that affect resistance and electric power the results showed that by increasing the number of bulbs within the electric circuits affected both electric power and resistance value in both series and. Ahow the length of a wire affects its resistance in this investigation i am going to measure how the length of a wire affects its resistance however there other factors which affects the resistance of a wire.

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 diameter of the wire will be kept the same so that it is a fair test the voltage will also be kept the same, although the readings may not be exactly the same each time.
How 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 current is the rate of flow of charge through a conductor. In this case, the temperature of the wire is a factor which affects measurements of its resistance discuss how this can be taken account of one approach is (as discussed above) to keep the wire at a constant temperature by immersing it in a water bath. How does the length of a wire affect its resistance introduction: this first report in physics will show the investigation of how the length of a wire affects its resistance. 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 how the length of a wire affects its resistance essay by vickerini, july 2005 download word file, 6 pages.
Extended experimental investigation: electricity the influential effect it has on resistance (virtual institute of applied science) if the length of a wire is increased then its resistance will increase if its cross-sectional area and temperature remains constant if the cross-sectional area increases then the. Resistance of a wire essaysaim: the resistance of a wire depends on certain factors investigate the effect of two of these factors ¡v some variables that will be relevant to this investigation are: of these the variables will be input and output voltages in experiment one, and length and resis. 1 introduction the problem i am investigating is the effect of temperature on conductivity and resistanceusing a suitable conductor such as a copper wire, the following experiment will study whether the temperature of a wire will affect the flow of electrical current through a conductor. In this article i will investigate what affects the resistance of a wire electricity flows in metals metal wires are made of millions of tiny metal crystals, and each crystal’s atoms are arranged in a regular pattern.
