Mastering physics solutions: resistance and wire length you have been given a long length of wire you measure the resistance of the wire, and find it to be. Does anyone know the calculation to measure the length of wire, by measuring the resistance, from one end of the wire on a spool to the other end. Furthermore, if you double the length of the wire, the resistance is roughly doubled for example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double in my main investigation i will see if this observation applies to my results. This experiment was conducted to find out how temperature affects the conductivity and resistance of a wire the experiment was done using copper wire. Class practical a simple investigation of the factors affecting the resistance of a wire students will find it easier to measure at a prescribed length if they. Investigating resistance of a wire the aim of this experiment is to find out how the resistance changes as the length of wire changes within the circuit changes.

Now if you increase the length of this wire to 20 cm its resistance r will be twice than it was at 10 cm if 100 people are running through a 20 ft broad passage. Measuring the resistivity of a wire student worksheet in this experiment you will be making measurements of voltage and current for a piece of metal wire, together.

Experiment 8: magnetic forces objectives 1 to investigate the magnetic force between two current carrying wires 2 to measure the permeability constant µ0.

The resistance in a wire increases as: the length of the wire increases the thickness of the wire decreases resistance - higher tier an electric current flows when. Saad mahmood – 06/09/2016 - resistivity of wire investigation of the relationship between the length of the wire and the resistance of the wire. Resistance is directly related to the length of a wire greater the length more the resistance and hence more heat loss.

In this experiment students can show that the resistance is directly proportional to the length (double one, double the other) whereas if the cross-section area doubles the resistance halves suitable contacts: each contact should be a disc of brass roughly 2 cm in diameter with a tube of brass brazed to the centre of one face at 90° to the. 1 measurement of electrical resistance and ohm’s law objectives in this experiment, measurements of the voltage across a wire coil and the current in the wire.

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. It is a simple thing to demonstrate a substance’s change in resistance with temperature i’m interested in finding out how you might discern a quantitative measurement of this change that is, how would you design an experiment so as to “attach a number” to the effect of resistance changing with temperature. Electrical resistance and conductance part of a series of articles about the electrical resistance of an electrical conductor is a measure of the difficulty to. Teacher notes the effect of temperature on electrical resistance abstract: this project allows students to experimentally discover the temperature dependence of resistance. Resistivity and conductivity the electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made experimentally, the dependence upon these properties is a straightforward one for a wide range of conditions, and the resistance of a wire. What is the relationship between the length of a metallic conductor and its resistance resistance is directly proportional to the lengtheg if a 10cm wire. First, the total length of the wires will affect the amount of resistance 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 after all, if resistance occurs as the result of collisions between charge carriers and the atoms of.
