Planning there are three different factors, which may affect the resistance of resistance putty these three factors are temperature, length and thickness to investigate the temperature it is very hard to make the temperature go up/down in certain intervals, it's also hard to connect the connecting wires to the.
R 7 analysing results my results support my predicted statement: the thinner and longer the wire the high the resistance and lower the currentthe thicker and shorter the wire the lower the resistance and higher the current as the length of the wire increases and the thickness decreases, the resistance increases and the decreases. There are four factors that affect the resistance of a wire: resistance is proportional to length if you take a wire of.
Kelvin (4-wire) resistance measurement wire resistance is very small because the accuracy of both instruments factors in to the final result. Purpose: to look into the factors of impacting the opposition of a wire in this experiment i will be utilizing a metal nichrome wire to demo the opposition when the length and breadth is changed.
3 factors affecting wire resistance 1 length, cross-sectional area, kind of material, resistivity and temperature: the ir re latio nships factors affectingfactors affecting resistanceresistance. 2 2-wire resistance measurements the 2-wire method is commonly used as it is the simplest and most straightforward method in 2-wire, you can get accurate measurements above 100 kω relatively easily for lower resistance (ohms) values, such as 100 ω, the interconnecting cabling can add significant resistance (ohms) which can greatly affect. Factors affecting resistance are followings [r= (ρl/a)] (i)larger the length, higher the value of resistance of wire (ii) lesser the resistivity of the material of wire, lesser is the resistance of the wire ie resistance depends on the nature of the material.
