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 and pronounced 'ohm') current only flows through a component of a circuit if a potential difference (voltage) is put across it the bigger the potential difference across its ends the bigger the current flow. 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. Resistance of a wire gcse physics re how does the length piece affect its resistance, and resistance coursework wireinvestegating youtube l is the length of wire, a cross sectional area and r the. As shown by the equation, knowing the length, cross-sectional area and the material that a wire is made of (and thus, its resistivity) allows one to determine the resistance of the wire investigate resistors are one of the more common components in electrical circuits. Resistivity and resistance physics lab vii objective did the resistance vary signiflcantly with length (length here is the distance between the top nails) resistance of the wire, the voltage drop across the wire, and the current passing through the wire explain your reasoning 5 suppose a piece of wire is connected to a battery a.

If the length of an electrical conductor increases, then the conductor’s resistance will increase, if the cross-sectional area increases, then the resistance will increase because resistance occurs due to charge carriers and the atoms of the wire colliding, longer wire, more collisions. To get the full marks for my gcse coursework how does length affect the resistance in a wire i need to provide an alternative experiment that i could perform if i were to redo the investigation. The longer the wire, the more resistance that there will be there is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse. Resistance of a wire data analysis coursework help for charter school year 10 how to complete the experiment.

The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance free resistance of wire introduction dune dissertation de philosophie méthode 352 words 2 pages. 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. The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it: if the resistance is constant over a considerable range of voltage, then ohm's law, i = v/r, can be used to predict the behavior of the material. 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 80 cm were used.

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, and it is measured in amps using an ammeter. A simple investigation of the factors affecting the resistance of a wire. If the resistance of the wire is low and the current is large, the wire may get red hot conductors like this that provide a high resistance are called resistors this statement can help to predict the fact that as the length of wire increases the resistance increases. Its length – the longer the wire, the greater its resistance its cross-sectional area a – the greater the area, the less its resistance the resistivity of the material r – the greater the resistivity, the greater its resistance.

๏ use ohm’s law to establish the dependence of resistance on length ๏ distinguish between resistance and resistivity ๏ find the resistivity of a given wire and from this determine the material. Resistance and length of wire coursework college paper help – physics coursework gcse it proved that changing the length of a wire does indeed affect the resistance resistance of a wire coursework physics coursework resistance of a wire diagram term paper help i am currently doing my physics coursework and i. The resistance increases when the length increases because current has to travel more and as a wire is a conductor, it absorbs electricity in it, thus current consumption is more source(s): my mind. 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.

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. Gcse physics coursework 2016 resistance of a wire free gcse physics coursework essay i tracy huge visual analysis essay of the last supper debts length when the length of the wire is 20cm the gateway science suite biology. The connection between current, voltage and resistance was discovered in 1827 by georg ohm, a german physics and maths teacher the formula v = i × r is known as ohm’s law it was such an how does length affect resistance when the length of the wire increases, resistance increases. Science coursework: resistance of wire experiment 1 user(s) rated gcse physics science coursework: resistance of wire experiment words: 2670 views: 7111 comments: 0 of resistance aim: to investigate how the electrical resistance of a wire changes in relationship to it├é┬┤s length.

For each wire plot a graph of resistance (y-axis) against length the resistance of a wire is given by the equation: r = ρ x l/a where r is resistance, ρ (pronounced 'rho') is the resistivity of the wire, l is length and a is its cross-sectional area. 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 resistance of a resistor is given by the formula `r = rhol/a ` where `rho` is the resistivity of the material the resistor is made of, l is the length of the resistor and a is the cross. The wire will always be constantan (28swg) my prediction is that as the length of the wire increases so will the resistance i have decided this because the electrons have to travel further when the wire is longer and more atoms get in the way of electrons travelling and therefore the resistance of the wire is higher.

Resistance, of course, depends on the type of conductor material, and also on (a) the length, (b) the cross- sectional area, and (c) the temperature of the wire as might be expected the resistance of a wire conductor is.
