In physics, the resistance of a strand of wire is affected by four factors: the material of the wire, its thickness, its temperature, and its length in my experiment, our group chose to study the effect of the thickness of wire on resistance. Below is an essay on how the length affects the resistance of a wire from anti essays, your source for research papers, essays, and term paper examples how the length affects the resistance of a wire. Factors affecting resistance 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. In this experiment, i predict that if the length of the wire increases, then the resistance will increase, in proportion to its length i think this because the longer the wire is, the more atoms will be contained within the wire.
Physics investigation resistance of wire essay i have chosen length of wire as one as my variables because it will give me a good range of results i will be. To investigate which factors affect the resistance of a wire i am going to run a series of tests to investigate whether the length of the wire affects the resistance hypothesis: get even a better essay we will write a custom essay sample on factors which affect the resistance of. Resistance and electrical conductivity environmental sciences essay assess the length of a wire for disparity in resistance of wire of this essay and no. I predict that the longer the length of wire, the higher the resistance is i think this because there are more metallic atoms in the wire, these will.
A piece of thin wire has higher resistance than a thicker with the same length, which means that it's length increases the thickness decreases is greater thick because apparatus wires varying. Wire resistance calculator & table quick calculator wire length write an essay response to our question for a chance to receive $1,000 towards tuition. Resistance of a wire essaysin this investigation i will carry out an experiment to distinguish how the length of a wire, disrupts the behaviour of the resistance throughout this investigation i will include my prediction, method, diagram, results and a graph to show the relationship between the l. Resistance of a conductor will decrease if its length and temperature remain constant method wire lengths (independent variable) of 20 cm, 40 cm, 60 cm and 80 cm were used.
For example, to calculate the resistance of a 250-foot #10-gauge copper wire, multiply length by the constant 104, then divide by the cross-sectional area for #10-gauge wire as the following steps show. If the length of an electrical conductor increases, then the conductor's resistance will increase, if the cross-sectional area increases, then the resistance will increase because resistance occurs due to charge carriers and the atoms of the wire colliding, longer wire, more collisions. The shorter and thicker a wire is, the lower is its resistance, as the electrical resistance of a wire is proportional to its length and inversely proportional to its cross-sectional area (except superconductors) the wire's resistance has the greatest effect on its performance. Free resistance of wire papers, essays, - length of a wire and resistance in a circuit my aim is to find out when i increase a length of wire there should be more.
Answer to what is the resistance of a 59-m length of copper wire 12 mm in diameter the resistivity of copper is 168×10−8ω. Introduction the resistance of a wire depends on certain factors some of these variables are listed below: • length of wire • diameter or thickness of wire. Answer to what is the resistance of a 54-m length of copper wire 15 mm in diameter the resistivity of copper is 168×10-8 ω skip navigation chegg home. 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 through a wire. 1problem a current of 076a flows through a copper wire 044mm in diameter when it is connected to a potential difference of 15v resistance problem find length.
Like the resistance to water flow, the total amount of resistance to charge flow within a wire of an electric circuit is affected by some clearly identifiable variables first, the total length of the wires will affect the amount of resistance. Below is an essay on resistance of a wire from anti essays, your source for research papers, essays, and term paper examples investigating the effect length has on the resistance of a wire aim. Question a portion of nichrome wire of radius 260 mm is to be used in winding a heating coil the required resistance of the coil ω (b) the length of wire you.
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. What is the resistance of a 050 m length of wire of the same material with a from physics 101 at keystone high school essay uploaded by cardiologyfansss. How does the length of wire affect resistance please explain well [while being scientific.
Resistance = resistivity × length / area therefore, if you stretch a (copper) wire its cross sectional area a will decrease and length l will increase, both causing an increase in resistance r resistivity is a constant for copper. Doubling the length will double the resistance, but the wire also must get thinner as it is stretched, because it will contain the same amount of metal in twice the length the volume of a cylinder is length cross sectional area, but in order to find the new cross section, you need to consider what the wire is made of. If r is the resistance of the given wire of length l then resistance per unit length = procedure: 1) the connections are made as shown in the circuit diagram.
