If cross-section of wire is uniform and the material is same, the resistance would be directly proportional to the length of wire, that is if length, l becomes x times resistance, r will become x times. , the resistance of a wire is proportional to its length, and inversely proportional to its cross-sectional area the constant of proportionality is called the resistivity of the material making up the wire. Resistance of a conductor depends on : 1 length of the conductor (more the length, more the resistance) 2 cross-sectional area of conductor (more the cross sectional area, less is the resistance. The key is to understand that charges are being pushed through the wire due to an electric field when the wire is short, the electric field is more concentrated and hence stronger how does the resistance of wire depend on its cross section how does the specific resistance of a wire depend on its length and radius.
Resistivity or resistance of a material depends on the following factors: 1 length of wire = resistance is directly proportional to length 2 area of cross section = resistance is inversely proportional to area of cross section 3 temperature = resistance of a conductor is directly proportional to temperature 4 kind of material. These results show that as the length of the wire increases, the resistance increases, as well furthermore, if you double the length of the wire, the resistance is roughly doubled for example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double. Ib physics investigation: does the cross sectional area of a wire affect it's resistivity electric resistance quantifies how strongly a conductor opposes to current flowthere are three to four factors that affect the resistance in a conductor one of which is the cross sectional area of the conductor, which is the conductor‟s.
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 resistance is the measure of how easy it is for current to flow through a wire. Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area as resistivity is affected by temperature, we can say. The force that acts between a pair of magnetic poles depends on separation distance and why does a wire that carries electric current become hot the electric resistance in a length of wire is doubled when the wire is twice as long. For the conclusion i would like to state that for every 5cm decrease in the length of nichrome wire, the voltage decreases by approximately 01 v, whilst the resistance decreases by approximately 07 (from 45-40cm), followed by 06 (from 40-35cm), followed by 05 (from 35-30cm.
Electricity the resistance of wires-length does the resistance of a wire depend on its length the resistance of a wire changes if its length changes this makes sense if you consider that there are a number of collisions between the electrons and the ions when electricity flows through 1 metre of a wire there are twice as many collisions when electricity flows through 2 metres and 3. Wire resistance calculator & table quick calculator wire length (feet) gauge (awg) wire resistance: ___ ohms (results are rounded to the nearest milliohm) advanced calculator write an essay response to our question for a chance to receive $1,000 towards tuition find out more. The resistance of a given conductor, r depends on: (a) the material of the conductor (b) area of its cross-section (c) length of the conductor (d) the temperature of the conductor for example, a long copper wire will have a higher resistance than an identical shorter.
R=(resistivity)(length of wire)/(area of cross section of that wire) resistivity of a substance depends on temperature and type of substance it is independent of dimensions of the wire. How the length of a wire affects its resistance how does the length of a wire affect its resistance essay how does the length of a a thermistor, a diode and so on its value depends on four things 1 what it’s made of metals are good conductors so have lower resistance than an insulator of the. 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 resistance is the measure of how easy it is for current to flow through a wire factors affecting the resistance of a conducting wire depend on temperature conductor like a metal 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. Electricity test grade 6 study play 2 length of material 3 diameter of material 4 temperature of material what are four factors that determine the resistance of an object (usually a wire) the resistance of a wire depends on the ___ and ___ of the wire, as well as ____ 1 circuits have devices that are run by electrical energy.
A high resistivity means that a material does not conduct well electric charge electrical resistivity is defined as the relation between the electrical field inside a material, the resistance value of a wire depends on three parameters: resistivity, length and diameter the wire has a length of 1500 mm and a diameter of 005 mm with. 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. Electrical resistance of an electrical conductor depends on the length of the conductor nickel-chromium wire - electrical resistance and temperature rise - electric resistance and temperature rise resistance resistivity ohms conductor length sponsored links. 3 students should come to understand that the resistance of a wire depends on its length, its cross sectional area, and the material out of which it is made with some students you could go further and introduce the concept of resistivity ρ, through the relationship r = ρ l / a where r = resistance, ρ = resistivity, l = length and a = cross.
