Wind chimes are arrangements of metal, glass, wood, shell, pottery etc, that produce sound when the wind blows past themthey can range in size from a few inches to several feet and retail from a few dollars to a several hundred dollars. The electrical resistance of a wire varies directly with the length and inversely with the square of the diameter of the wire if a wire 432 feet long and 4 millimeters in diameter has a residence of 124 ohms, find the length of a wire of the same material whose resistance is 144 ohms and whose diameter is 3 millimeters. Thickness of the wire: the thicker the wire is the more free electrons in the current can spread out moving over a larger area therefore there is a smaller chance of colliding with the positive ions, thus it decreases the resistance.
Aim: to find out the effect on resistance, when the length of wire is changed in my experiment i will firstly get 3 100 cm wires made of constantan all of different thickness', one of 28 one of 40 and one of 56cm we will set up the experiment like this diagram shows an ammeter will be. I have chosen length of wire as one as my variables because it will give me a good range of results i will be able to compare the results from the shortest wire to the longest i will start at 100cm then i will take 10cm off each time until i get to 50cm. If you find that a paragraph contains more than one idea, you may need to reorganise your essay so that your ideas are developed more logically look at the other paragraphs in your essay paragraphs should all be of roughly similar length.
My hypothesis was correct the nichrome wire proved that the longer the wire, the higher the resistance ohm's law states that the current flowing through the circuit is directly proportional to the voltage applied. The length of the wire doesnt practically have an effect on the current, but it has a considerable effect on the voltage profile across the wire provided that the wire is feeding a considerable amount of load in the intermediate path or at the extremity. Open document 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. National wire & cable custom cable manufacturing & molding • wwwnationalwirecom order desk 323-225-5611 7-2 cable designers guide how to specify cable in the absence of your own cable specification, the following checklist will assist you to completely specify.
(b) the length of wire you must use to wind the coil m (c) a 0700-v potential difference is maintained across a 150-m length of tungsten wire that has a cross-sectional area of 0600 mm2. Question 588576: the resistance of a wire varies directly with its length and inversely with the square of its diameter if 100 feet of wire with diameter 001 inch has a resistance of 90 ohms, what is the resistance of 68 feet of the same type of wire if its diameter is 002 inch. The free length of compression spring is the maximum length of spring in free condition it is equal to solid length plus the maximum deflection of spring and clearance adj to two coils. Essay on the wire - essay wire it has become a cliché to describe the city of baltimore as one of the leading characters in the wire, a pitfall that this collection neatly sidesteps. The electrical resistance r of a wire varies directly with its length and inversely with the square of its diameter d 100 m of wire with diameter 3 mm has resistance of 8 ohms.
The length of the wire affects the resistance of the wire because the number of atoms in the wire increases or decreases as the length of the wire increases or decreases in proportion the resistance of a wire depends on the number of collisions the electrons have with the atoms of the mat. For the length i will test ten different lengths of wire, increasing by a set amount each time to make it easier to plot a graph the range of which i will investigate will be between 10cm and 100cm, the readings i'm going to take will as following 10cm, 20cm, 30cm, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm and 100cm. An analysis of length of a wire affects its resistance pages 4 words 1,445 view full essay sign up to view the complete essay show me the full essay. The resistance, r, of a wire varies directly as its length and inversely as the square of its diameter if the resistance of a wire 3900 feet long with a diameter of 014 inches is 18625 ohms, what is the resistance of 300 feet of the same type of wire with a diameter of 015 inches.
Reflective essays describe an event or experience, then analyze the meaning of that experience and what can be learned from it what makes an essay reflective is that the writer is analyzing a past event from the present. Calculate the magnitude of the magnetic force on a 240m length of wire stretched between two towers and carrying a 180a current the earth's magnetic field of 60×10−5t makes an angle of 45∘ with the wire. The half-perimeter wire length (hpwl) model is commonly used because it is reasonably accurate and efficiently calculated the bounding box of a net with p pins is the smallest rectangle that encloses the pin locations [6. The resistance, r, of a wire varies directly as its length and inversely as the square of its diameter if the resistance of a wire 1200 feet long with a diameter of 016 inches is 6848 ohms, what is the resistance of 3600 feet of the same type of wire with a diameter of 002 inches.
If the external surface of the cylinder (excluding the ends) can dissipate 05 w per cm2 at the permitted temperature rise, find the length of the cylinder and the diameter and length of the wire. Show transcribed image text the resistance of a wire varies directly with the length of the wire and inversely with the square of its radius a wire with a length of 500 cm and a radius of 05 cm has a resistance of 15 ohms. The wire that will be used in the experiment is nichrome 30 wire which has a radius of 0000125m and also nichrome 22 wire, with a radius of 00346mm (346e-5m) ohm's law deals with the relationship between voltage, current and resistance.
