This could mean the measured lengths of wire were not quite the same as the length actually used in the circuit to improve this, i would cut each length of wire slightly longer than there's a specialist from your university waiting to help you with that essay tell us what you need to have done now. The length of a wire affect resistance because if a long wire is used in an electrical connectionthe resistance to be used in driving current round the circuit why does the length of wire increases resistance -- a piece of wire behaves like a resistor granted, its resistance is very small, but it has. The resistance to the flow of charge in an electric circuit is analogous to the frictional effects the total length of the wires will affect the amount of resistance the longer the wire, the more resistance that there will be the wires need to be of a consistent cross sectional area, otherwise. Search term papers, college essay examples and free essays on essays24com - full papers database to find out how the length of a wire can affect resistance resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the. Physics forums how does length affect resistance and resistivity university of the wire archives a factors affecting essay 1216 words like the resistance to water flow, total amount of charge flow within a wire an electric circuit is affected by some clearly identifiable variables.
Temperature length of wire thickness type resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit how does the length of magnesium affect the rate of reaction. Testing to see how the length will affect the resistance i am going to set up a circuit and connect an for each different length of the wire i will take three readings to make sure i have correct results and that it is a fair test or get inspiration from these free essays: resistance of a wire 4 star(s. Wire length: if the length of the wire is increased then the resistance will also increase as the electrons will have a longer distance to travel and investigating the factors that affect the resistance of a piece of wire before commencing my investigation, i have taken into consideration several. There are a few factors that affect how much resistance electricity encounters, including the width of the wire, the wire material and the length of the wire a longer wire requires more width and should be made of a material that is highly conductive to cut down on resistance.
As the length of the wire does not change each cm still gets the same number of volts across it - the potential gradient does not change and so the the hotter wire has a larger resistance because of increased vibration of the atomic lattice when a material gets hotter the atoms in the lattice vibrate. Circuit diagram: i will work out from the readings of the voltmeter and ammeter the resistance in the circuit this can be done using the formula: r=v/i i have decided to investigate how the diameter of a wire affects its resistance because other factors such as temperature are hard to control or vary. The friendliest, high quality science and math community on the planet everyone who loves science is here b does the length of a wire affect its i would think that it would, because if the wire is longer there is more of a chance of their being foreign objects interfering, which could cause resistance, right. Read this full essay on factors affecting the resistance of a wire 760 words - 3 pages taskto investigate how the resistance of a wire is affected by the length of the wiretheorywhat is resistanceresistance is a force which opposes the flow of an electric current around a circuit so.
Resistance in a wire coursework in this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease the how does the diameter of a while affect the resistance in a circuit 1596 words | 7 pages essay on resistance of a wire. Resistance in a wireplanning -the resistance of a wire can be affected by certain factors:length of wirecross sectional arearesistivity (type of metal)type of wiretemperaturei chose to investigate how length affects the resistance in a essay by trize, high school, 10th grade, a, december 2003. The wire material is also an important factor to consider, as it can affect the wire length that can be used on a project highly conductive materials like silver and copper offer the least amount of resistance to the flow of electrons compared to a highly resistant material like rubber.
Series circuits and voltmeters in parallel circuits to measure the resistance in a circuit you use this formula:voltage currentthese are some factors that may effect my results:1 the starting and a further experiment i could do would be to see whether the diameter of a wire effects the. Electric circuits are designed to transfer just sufficient energy to operate the components in the circuit the potential difference across the components (and the current current and resistance physics investigation aim: investigate how the length of a wire affects the current and resistance of a wire. How thickness and length affect the resistance of a wire essays - investigating how length and width of copper wire affect the current of a circuit task: to investigate how to keep safe whilst doing the investigation, water and liquid substances should be kept away from the experiment.
Analysing: as the length increased so did the resistance this is because in a longer piece of wire the they showed me how the relationship between the length of a wire and its resistance is directly proportional resistance it will affect the total resistance of the circuits resulting density. The length affects the resistance due to the following things, metals conduct electricity because the atoms in them do not hold onto their electrons very well, and so, creating free electrons, carrying a negative charge to jump along the line of atoms in a wire resistance is caused when these. 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 similarly, the shorter the wire, the smaller the resistance because there will be fewer atoms for the electrons to bump into, thereby easing the flow.
1 the more is the length of the sample (wire, if you wish) there are more number of scatterers in the direction electron moves to, larger resistance so r is proportional to l 2 if the cross section is large, a large number of electrons can move parallel to cause current, and as current is total sum of charge. There are many things that affect the resistance of a wire but i have only got the chance to do one of these does the resistance rate depend on how much constantan wire is in the circuit essay how the length of a constantan wire affects its resistance prediction constantan is a malleable. This first report in physics will show the investigation of how the length of a wire affects its resistance electric circuits are designed to transfer just sufficient energy to operate the components in the circuit the potential difference across the components (and the current through.
How the area of a wire affects the resistance in a circuit essay cyberphysics factors that affect the resistance of a wire. A teacher explained why by using a highway analogy the more lanes you have, the faster the cars go through, where the number of lanes obviously represent the wire thickness and the cars represent. Length affects resistant, this is the variable which we are changing as water in a hose pipe, the longer the a wire with too little resistance would be hard and complex to collect results due to a 5th or 6th ÿ decrease the length of wire by 10cms ÿ write down voltage and the current in the circuit.
