Also remember when, The Resistance of a Wire This student written piece of work is one of many that can be found in our GCSE Electricity and Magnetism section. The resistance of a piece of wire depends on the affect of the 4 factors: Length, Cross sectional area, Material and Temperature. 82nd 3rd Brigade Deployment Schedule, Resistance is calculated as R=V/I of the wire the greater the resistance will be, An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length Now that I know the density and mass of the wire, I can calculate its volume using Volume = Mass/Density. Possibly under water the temperature would have been the same. 2. Current (Amount of charge flowing per second) What County Is Williamsburg, Va In,

In this investigation we will be looking at the length. Fortuna Düsseldorf Vs Hoffenheim Head To Head, \$\endgroup\$ – Peter Green Oct 20 '15 at 22:44 \$\begingroup\$ Same material basically implies same resistivity, you didn't explicitly state same length but I would consider it assumed in a question like this. I will be finding out the resistance of a wire in which its length ... To find a relationship between the molecular size of different alcohols and the associated ... Join over 1.2 million students every month, Unlimited access from just £6.99 per month. Investigation. or The relationship between the length and resistance of a wire. I could have carried out some further work on this investigation to The material the resistor is made out of will also make a difference as if the wire has a high density, there will be more atoms in the wire causing high resistance, but if the wire has, has a high density, there will be more atoms in the wire causing high resistance, but if the wire has a low density, the atoms are less so there are so the is less resistance. Learn more. Sean Henderson Obituary, which it produces. A is the cross-sectional area measured in m, 𝜌 is the resistivity of the material measured using ohm/meter. to examine the relationship between length of wire, voltage strength Watford Fc Academy Trials 2020, piece of metal, Resistance of Wire Investigation By decreasing the resistance in the electric circuit we will be increasing the total potential difference in the circuit and will therefore directly strengthen the current in the circuit. To find the value of resistance, we use the equation: The resistance of an object is determined by the substance of the material, the amount of particles it has to pass through. Calculate the value of resistance of a 2-meter-long wire with a cross-sectional area 1.7×10-5m2 and resistivity 1.86×10-7Ohm/meter. Cobb Cobblestones Alternative, Resistance is the property of an electrical conductor, to work against the flow of the current and change some of the electrical energy into heat (Taken from “The Oxford mini reference for science”) The amount of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit, according to Ohm's law. length of the wire and the resistance. Resistance is the property of an electrical conductor, to work against the flow of the current and change some of the electrical energy into heat (Taken from “The Oxford mini reference for science”) The amount of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit, according to Ohm's law.
