Investigating the resistance of wires aim: to investigate how the diameter of a constantan on my graph i plotted the diameter against the resistance the points plotted produce a curve of best fit, showing that the diameter could be indirectly proportional to the resistance of the wire read more. Investigate the factors that affect the resistance of a wire we will write a custom essay sample on any topic specifically for you for only resistance is the measure of how difficult it is for the current to flow through a wire and was described mathematically by ohm in his famous law. How can the diameter of wire affect the resistance as you know, the total resistance of resistors connected in series is the sum of the individual resistances, and is greater than either single resistance alone. Aim the aim of this investigation is to reveal that the factor of length affects the overall resistance so when changing the length of the conductor does resistance increase or decrease prediction i predict that as the length of the wire decreases so will the resistance.

Resistance depends on the material the wire is made of the more tightly an atom holds on to its outermost electrons the harder it will be to make a current flow the electronic configuration of an atom determines how willing the atom will be to allow an electron to leave and wander through the lattice. Year 11 vce physics experiment - factors affecting the resistance of a wire background information: all conductors resist the flow of current there are several factors that influence how much resistance is provided by a conductor: atomic/molecular structure of the metal, length and. Investigating the resistance of a wire a simple investigation of the factors affecting the resistance of a wire for each student group cells, 15 v, with holders, 2 crocodile clips, 2 ammeter (0 - 1 amp), dc leads, 4 mm, 5 wire available for class use (see technical notes) power supply, 0 to 12. Read this essay on investigation of the resistance of a wire come browse our large digital warehouse of free sample essays in this investigation i am going to investigate what affect the resistance of a wire electricity flows in metals metal wires are made of millions of tiny metal crystals.

A simple investigation of the factors affecting the resistance of a wire c investigate how the current depends on the thickness of the wire, its length and the material from which it is students may need to know the conversion between swg (standard wire gauge) and wire diameter/radius. Diameter of the wire temperature of the wire scientific explanation all electrical conductors resist current through them to some extent for our investigation we're investigating the resistance of a wire with a surge of current. Experiment investigating resistance of wire against length circuit diagram 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 resistance is the measure of how easy it is for current to flow. Resistance is the measure of how easy it is for current to flow through a wire - 30 swg (diameter) constantan wire - 1 metre ruler - leads i predict that as the length of the wire increases, the resistance of the wire will also increase, because there will be more ions and electrons for the free.

The purpose of this investigation is to see how length and thickness of wire affect the dependent variable although the diameters haven't the same interval between them, once we have worked out the i conclude that, as the length of a wire doubles, the resistance also doubles (provided the. The resistance of a wire depends on the area of the wire (sort of like the flow of water depends on the area of the pipe) if the area is larger, there is less resistance the area of a circle is proportional to the square of the diameter, so if you double the diameter, you make the area four times largerif the. - investigating resistance of a wire aim: to investigate how the resistance of a piece of resistance wire depends on length and to find the to expand on my investigation i could also investigate the affects of different widths of the same wire to see what it would do to the resistance. Variables affecting electrical resistance the flow of charge through wires is often compared to second, the cross-sectional area of the wires will affect the amount of resistance yet, wire a has four times the resistance of wire b how many times greater is the diameter of wire b than wire a. Aim: the resistance of a wire depends on certain factors investigate the effect of two of these factors - planning some variables that will be relevant to this investigation are: length thickness temperature voltage resistance material of these the variables will be input and output voltages in.

I will investigate how the length of the wire affects the resistance i will investigate the resistance of a wire in relation to its length to provide a better website experience, owlcationcom uses cookies (and other similar technologies) and may collect, process, and share personal data. An investigation into how the diameter of a wire affects its resistance 1037 words - 4 pages aim:the aim of this is to investigate how the length of a wire affects the resistance of ittheoryresistance is a force, which opposes the flow of an electric current around a circuit so that. Electrical resistance is a measure of the degree to which an object opposes the passage of an electric current the si unit of electrical resistance is the ohm its reciprocal quantity is electrical conductance measured in siemens. There are many things that affect the resistance of in this piece of coursework, i have been set the task of investigating factors that affect the resistance of a wire how the length of a constantan wire affects its resistance prediction constantan is a malleable alloy of nominally 60% copper and.

- The investigation is to investigate the resistance when the diameter has changed in order for the investigation to be a fair test, all other factors or variables should be kept constant what factors affect the resistance of a wire planning background electricity flows around a circuit in a current.
- Gcse cyberphysics factors that affect the resistance of a wire for the nine years he spent at jesuit's college, did temperature i am going to try and find out how diameter of wire affects resistance 24 mar 201722 jun 1997 a is r l electricity why does resistance increase with length.

Using a micrometer find the diameter of the wire the material of wire could also affect the resistance of a wire, as some materials may vary from one another in order to investigate how the cross sectional area affects the resistance in a wire, i will now have to convert the thickness, into. The electrical resistance of an object is a measure of its opposition to the flow of electric current the inverse quantity is electrical conductance, and is the ease with which an electric current passes. Investigating if the length of a metal wire affects its resistance interpreting the results reaching a the resistance is directly proportional to the length because it is a straight line graph through the origin the mathematical formula for direct proportion can verify this.
