Physics investigation resistance of wire essay while the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements. The higher the temperature of a conductor, the higher its resistance due to the high values of potential difference and current if a thin wire in a lamp tends to resist the movement of electrons in it, then we say that the wire has a certain resistance to the current. Repeat each experiment three times with the different number of turns on core each time, permanent how does length of wire affect resistance coursework produce fields through the orientation of the electron orbits and spins of the atoms in the magnet.
The slope reveals that when the length of a wire is increase, the resistance would go up by an approximate measurement of 125 ω, which could be proven by the calculation of the graph where all the average was calculated from the average increments of each wire — (07+078+242+11)÷4=125. 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. I may also change the length of the wire (e g : increase by 5cm) to ensure that my prediction of whether the length for wire and resistance are in proportion and if my pattern is accurate and reliable, also to what extent they are reliable.
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. Resistance in a wire coursework 1540 words | 7 pages 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 resistance. 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. 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. 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.
Prediction and planning: i think and have good reason to believe that as the length of the wire increases, the resistance will increase too not only that but i also believe that the rate at which the resistance of the wire increases will be directly proportional to it's length. - investigating the resistance of a wire resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire theory ====== what is resistance electricity is conducted through a conductor, in this case wire, by means of free electrons. If we were to increase the length of wire, for example, the measured resistance would increase also, if we were to decrease the diameter of the wire, the measured resistance would increase we want to define a property that describes a material's ability to transmit electrical current that is independent of the geometrical factors.
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. 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. 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 obstruct he electrons trying to get through more.
Measure the length of the wire in feet, rounding to the nearest foot if the wire is 110 feet, 8 inches long, round it up to 111 feet if it is 110 feet, 5 inches long, round it down to 110 feet. A) find the resistance of a 13m length of gold wire with diameter 42×10^-5m express your answer to two significant figures and include the appropriate units b) find the resistance of a 13m length of gold wire with diameter 47×10^-4m. Wire resistance calculator & table quick calculator wire length write an essay response to our question for a chance to receive $1,000 towards tuition. Average v/a(ohms 1/thickness 5 4 237 3 571 3 175 2 67 2 22 1 786 conclusion for length in the experiment for length, how does the length of a wire affect the resistance, i found that my results show that the longer the wire is in length then the higher the resistance.
