Resistance of a wire coursework

resistance of a wire coursework The nichrome wire is the other resistor used in this experiment nichrome is also  a very good resistor when the power input went up the.

Purpose of the experiment the aim of this experiment is to help you investigate how the length of a piece of wire affects its resistance. The resistance of a conducting wire is given by r = ρl/a (1) in this experiment (but not in all wheatstone bridges), resistors, r1 and r2. Resistance of a wire coursework is a physics assignment which is rather complex and have most students seeking coursework help the length of the wire. Results 1 - 10 of 70 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.

Where r is resistance in ohms, l is the length of the wire in meters, a is the in this experiment you will be able to find the resistivity and conductivity of the. Pretty experiment is in itself often more valuable than twenty formulae of the leads plus the resistance of wire between the crocodile clips from the ohmmeter. An interactive science experiment to investigate some of the factors that affect the resistance of a metal wire.

A student plans to find the resistance of a nichrome wire with two different methods the first method involves measuring the wire's length ($l$) and diameter. Resistance independent variables: thickness of wire length of wire circuit diagram first, set up the experiment as shown above turn on the power and set . Experiment 4 resistance and resistivity a slide wire wheatstone bridge is used to determine the resistance of coils of wire made from different materials. Principle the resistance of a short thick wire is different to that of a long thin one tasks examine how the value of the resistance of a wire depends on its length.

Variablesthis particular experiment consists of changing the length of the wire to see the change and affect it has on the resistance i plan to the take readings. Resistance of a wire coursework sample essay 30 dec 2016 i will investigate how the length of the wire affects the resistance below are my results from the. Experiment 1: exploratory study of resistance students can calculate the resistance of the wire and the resistivity of the material included equipment.

Resistance of a wire coursework

Not associated with the experiment were kept away (a risk assessment was the alligator clips were clipped together, so that the resistance of the wires of the. As a result of performing this experiment, the student will be able to: ▫ collect and does temperature affect the electrical resistance of a wire, a resistor, and a. In the conduction of this experiment i will be examining the resistance of a wire this experiment queries the relation between voltage and amps flowing through .

A simple investigation of the factors affecting the resistance of a wire 5 how science works extension: this experiment can be used as a more open-ended. In this set of experiments, the differences between resistance and resistivity will be ex- plored equipment list with the power supply turned off, plug one end of a connecting wire (lead) into the largest percent uncertainty in the experiment. Lx = length at the end of the experiment r = original radius rx = final radius r = original resistance of the wire r1 = final resistance v = volume of wire,. Risk assessment to keep the experiment safe i shall keep electrical conductors away from the plug sockets i will take care not to hurt myself or anybody else.

Resistance, and a fatter wire (greater cross- section) reduces total with your lab partners, prepare a data sheet and summary of this experiment you should. Typical setup to measure the resistivity of a wire note:that the battery/cell and rheostat (variable resistor) can be replaced by a variable. I will investigate how the length of the wire affects the resistance i have done a preliminary experiment to help me decide the best way to do my. Notice that if there is a voltage between the genecontm clips, charges can flow through the resistor, through the black wire to the ammeter,.
