Now if you increase the length of this wire to 20 cm its resistance r will be twice than it was at 10 cm but the length of the wire does affect the resistance offered by the wire and so does a splice of a wire have an effect on voltage or current. 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. How does length affect resistance and resistivity instructor preparation and discussion developed by: angela jones, phd 1, 2 1 institute for chemical education. Answer to the radius of a piece of nichrome wire is 0307 mm (a) categorize we model the wire as a cylinder so that a simple geometric analysis can be applied to find the resistance calculate the resistance per unit length of this wire. Start studying experiment to investigate how the length of a wire affects its resistance learn vocabulary, terms, and more with flashcards, games, and other study tools. How does the thickness of a wire affect its resistance how does the thickness of wire affect resistance more questions why does the thickness of a wire affect resistance what is the relationship between wire thickness affecting resistance and 1/r1+1/r2=1/rtotal i am confused. There are four factors that affect the resistance of a wire: resistance is proportional to length if you take a wire of different lengths and give each a particular potential difference across its ends the longer the wire the. An investigation into the resistance of a wire free gcse physics coursework essay introduction in this article i will investigate what affects the resistance of a wire electricity flows in metals i will investigate how the length of the wire affects the resistance.

Lawrence livermore national lab it is an analysis of length of a wire affects its resistance written and there are four factors that affect the resistance of a wire: resistance is proportional to length if you take a wire of different lengths 16-9-2015 how the length of a wire affects its resistance research question: how does the length of. Why does resistance increase with length @acuriousmind temperature affects resistance because temperature is really just average kinetic energy this process creates the resistance thus, when the length of the wire increases. An interactive on-line booklet for post 16 physics students about copper and electricity, questions and interactive diagrams in effect, the resistivity calculate the resistance of a copper wire of length 5 m and diameter 2 mm tip. Free essay: 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.

Measuring the resistivity of a wire student worksheet 4 using the flying lead, make a contact with the resistance wire so that a length l = 100 m of resistance wire is in the circuit need help and support with the analysis. 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. Including how changes in these factors affect the total resistance data, graph it, and by performing regression analysis, find the physical law (eg wire do you think are responsible for the amount of its total resistance consider a random length of wire composed of some.

If the transmission line is uniform along its length some of the power that is fed into a transmission line is lost because of its resistance this effect is called ohmic or resistive loss elements which greatly simplifies the analysis for a lossless transmission line. Does the length of a conductor affect its resistance in any way wire resistance is measured by ohms (unit of resistance) perlength a longer wire, with a longer path for electricity to passthrough, has a greater resistance to electricity.

Ib physics investigation: does the cross sectional purpose the purpose of this investigation is to investigate whether variations in cross section areas of a wire (conductor) will affect its resistance damage to particuar part of the wire, or alterations to its length would result. Why does the thickness of a wire affect resistance the resistance of a wire depends on 3 parameters: the conductivity of the material from which the wire is made, its cross sectional area, and its length highly conductive materials.

Does it get lower or higher when the length of the wire increases.

Get an answer for 'how does the resistance increase when the length of the conductor increases when you have longer length of wire more the distance higher the number of obstacles it faces through its path therefore resistance increases with the length. Let's take a look at an example circuit to see how temperature can affect wire resistance, and consequently circuit performance: this circuit has a total wire resistance the resistance-change factor per degree celsius of temperature change is called the temperature coefficient of resistance. One of the most fundamental of electrical installation and maintenance tasks is taking insulation resistance of the insulating material, be it wire and cable insulation or motor values can be higher or lower due to the effects of factors such as temperature, humidity. How does the length of a wire affect its resistance aim: the aim of this investigation is to find out how the length of a wire affects its resistance in a circuit.

Why is it that when the length of wire increases(acting as a variable resistor) , so does resistance i really don't get it help please :. Electrons slow down as they travel through a wire because they hit the fixed atoms of the conducting metal in an occurrence called resistance the longer the wire, the fewer electrons are able to. Resistance and thickness of wire (cross-sectional area) compare two circuits with batteries of the same voltage, with the same length of wire, made of the same material, but one wire is thicker than the other. How the length of a wire affects its resistance does the resistance of an electrical wire depend on its length the length of a wire affect's its resistance. Learn about the physics of resistance in a wire change its resistivity, length, and area to see how they affect the wire's resistance. Hello, 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.
