The wire showing its resistance essay
When electricity flows through a wire, its electrons must move past the individual atoms of the wire material these impacts slow down the electrons and can eventually stop their flow 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. The electrical resistance, r of this simple conductor is a function of its length, l and the conductors area, a ohms law tells us that for a given resistance r, the current flowing through the conductor is proportional to the applied voltage as i = v/r. Thanks a2a suppose you have a wire of 10 gm weight and its length is 10 cm now if you increase the length of this wire to 20 cm its resistance r will be twice than it was at 10 cm if 100 people are running through a 20 ft broad passage they will easily get across it, but if the same no of. Physics investigation of resistance aim: to investigate how the electrical resistance of a wire changes in relationship to ités length prediction: i think that as the length of the wire increases so to will the resistance of it.
C calculate the resistance of the lamp at its running temperature d now, for several different values of pd, measure the current through the lamp plot a graph of your results this graph is known as the voltage-current characteristic of the lamp. Read the wire news, latest news from india and world including current news headlines on politics, business, science,culture and more only on thewirein. A still of aidan gillen and robert wisdom on the wire slate is celebrating hbo’s marathon broadcast of the remastered the wire by republishing some of our best coverage of the show this article. Investigating resistance of a wire essay examples resistance my tables and graph show this because it can be seen from either of them that as the wire length increased so did the resistance and as the wire length decreased , so did the resistance.
The resistance of a wire depends upon its length, area of cross-section, type of material, purity and hardness of material of which it is made of any working temperature resistance of the wire is proportional to the length of the wire r α l. Originally answered: how does the resistance of a wire depend on its length there is a formula which defines the resistance (r) of a wire which is defined r = pl/a “p” is the specific resistance of the wire material, “l “is the length of wire and “ a” area of cross section of wire. 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 resistanceresistance is the measure of how easy it is for current to flow through a wirecurrent is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter to help me plan my investigation i have completed a. As the diameter of a wire increases, its resistance will also increase the correct answer is 'false' in a circuit with two or more resistances in series, the total resistance in the circuit is the sum of the resistances.
As shown by the equation, knowing the length, cross-sectional area and the material that a wire is made of (and thus, its resistivity) allows one to determine the resistance of the wire investigate resistors are one of the more common components in electrical circuits. How does the length of a wire affect its resistance introduction: this first report in physics will show the investigation of how the length of a wire affects its resistance. When the wire was at 020m, the resistance was 3865 î© and when the wire area cross sectional was 346e-5m the resistance was 3068 î© knowing that per the original hypothesis that “the wider the cross sectional, less resistance so, when the wire was at 020m, it agrees with the hypothesis. 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.
Home free essays factors affecting the resistance of a wire factors affecting the resistance of a wire essay b pages:5 words: which would show up on the voltmeter, i will record the reading of the ammeter we will write a custom essay sample on factors affecting the resistance of a wire specifically for you for only $1638 $139. This first report in physics will show the investigation of how the length of a wire affects its resistance for starters i will go through the main definitions, to get a better knowledge of what is going to happen. The wire, which has just begun its fourth season on hbo, is surely the best tv show ever broadcast in america this claim isn’t based on my having seen all the possible rivals for the title, but. If you cut directly and squarely across the width of a wire then you will look at the end and it looks like a circle the area of that end is the cross section area, which is pi x r^2 a larger cross section area results in lower resistance per foot when the type of wire is the same its usually.
The wire showing its resistance essay
Moreover when average resistance is calculated, it is very obvious that the resistance of w1 is larger than that of w2, thus proving my hypothesis correct that if the cross sectional area of a wire are increased (is larger) then the resistance will decrease (will be lesser. Hbo's the wire: series review and analysis the hbo drama, the wire, recently completed its fifth and final season it would be harder to find a serial that was better written, developed, acted, and which stayed truer to its themes over the course of multiple seasons. Considering the quality and scope of the show, it was inevitable that the wire would go down in the pantheon of all-time great tv shows but the ratings during the show’s five-season run weren.
Observe changes to the equation and wire as you play with the resistivity, length, and area sliders sample learning goals predict how changing each variable will affect the resistance. 1 introduction the problem i am investigating is the effect of temperature on conductivity and resistanceusing a suitable conductor such as a copper wire, the following experiment will study whether the temperature of a wire will affect the flow of electrical current through a conductor.
