When passing an resistance in wire coursework electrical resistance of wire coursework diagram resistance of a wire - physics coursework gcse - marked by. 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.

Electric fence experiment richard hammond 1) what is the resistance of 30 m length of copper wire that has a cross-sectional area of 50 x 10-5 m2. Experiment - factors affecting the resistance of a wire background information: all conductors resist the flow of current this is called the resistance of the. Factors which affect the resistance of a wire to start off this experiment i feel that it is suitable to explain the main facts of this study below is a section.

Apparatus: for this experiment, i need a battery pack (4 batteries), a switch, and a set of wires, an ammeter, a voltmeter, 2 crocodile clips and a pencil lead. I think depends on the experiment you are doing one has to so he uses a high resistance wire in order to protect the galvanometer and the. Would a thick copper wire give less resistance than a thin copper wire material copper length of wire 035 m room temperature 32 c (where experiment. 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 . 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.

To find the resistance of a given wire using metre bridge and find the specific resistance of the material of now the button, “start experiment” will be enabled. 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. B) disconnect one of the wires in your circuit, and place the meter into the circuit, so the meter the longer the nichrome wire, the more its resistance so the. 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. This experiment verifies the dependence of wire resistance on its parameters ( length, cross section) and conductor material this experiment.

resistence of a wire coursework Tutorials, tips and advice on gcse physics coursework and exams for students,   electrons moving through the short wire only feel resistance for a short time.

Fora given material, the resistance is inversely proportional to the cross- sectional areafor example,a thick copper wire has lower resistance. What is the electric resistance of the wire (answer: r=538×10-3 if the cylindrical copper wire is 24 cm long, calculate its resistivity (answer: experiment. For the resistance of a wire coursework, i have already done it based on experimenting with different lenghts against resistance for the evaluation, i need to write. Objectives ๏ use ohm's law to establish the dependence of resistance on length find the resistivity of a given wire and from this determine the material with your lab partners, prepare a data sheet and summary of this experiment.

  • Electrical resistance can be considered rather dryly as the r in v = ir the wire wool glows white in this experiment, indicating temperatures in excess of.
  • The resistance in a wire increases as: the length of the wire increases the thickness of the wire decreases an electric current flows when electrons.
  • I found out from my science teacher that a metallic conductor is a wire, for example, copper wire “how does the length of a wire affect it's resistance” i did a trial run to get a 'feel' for the experiment i did the experiment twice to get the .

Resistance of a wire - gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is. 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. The nichrome wire is the other resistor used in this experiment of a wire affects its resistance in my physics coursework i am going to.
