Cross sectional area affect the resistance

cross sectional area affect the resistance How does area of cross section of a conducting wire affect the current and resistance .

Due to limited resources, we augmented the cross-sectional area by adding more wires in parallel, instead of simply using thicker wires my hypothesis was that as you increase the cross-sectional area, the resistance decreases, which would result in a higher peak current. The smaller the cross sectional area of the wire, the less channels of electrons in the wire for current to flow, as the energy is not spread out as much in a wire that has a larger cross sectional area, the resistance will be higher. Area of cross section is inversely proportional to the resistance of the conductor therefore more the area of cross section more is the current flowing through the wire and less the resistance kj 10 years ago.

Electrical resistance and conductance jump to navigation jump to search part of a series of articles about a is the cross-sectional area of the conductor . Factors affecting the resistance of a conductor in this task you will analyse the results of several experiments to determine how the following factors affect the resistance of a conductor: cross-sectional area. Thus, there are three ways resistance in the stretched wire increases: (1) doubling the length, (2) reducing the cross sectional area according to poisson's ratio, and (3) the piezo-electric effect share | cite | improve this answer. An investigation into the resistance of a wire free gcse physics coursework essay cross-sectional area (which could potentially affect the results because .

The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made experimentally, the dependence upon these properties is a straightforward one for a wide range of conditions, and the resistance . How resistivity affects the resistance of conductors made from different materials the resistivity formula relating length, cross sectional area and resistivity to resistance. When the cross sectional area of the wire increases, the resistance decreases r=(resistivity coefficient x length)/cross sectional area answer - none of the above 1 resistance increases in .

The measured resistance will vary directly with the distance the electrical resistivity is an intrinsic property and should therefore be independent of length and cross-sectional area, but in this activity,. This case, the resistance is proportional to the cross-sectional area of the wire the cross-sectional area of the wire is determined by the formula, πr2 the. The si unit of electrical resistance is the ohm (ω)an object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. Physics how does the diameter or cross-sectional area of a wire affect its resistance aim: i am going to investigate how the diameter, or gauge, of a wire affects its resistance. To keep the topic simple, it can be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object increased speeds result in an increased amount of air resistance.

Cross sectional area affect the resistance

cross sectional area affect the resistance How does area of cross section of a conducting wire affect the current and resistance .

Category: papers title: factors which affect the resistance of a wire my account the length and cross-sectional area of the object, and by the temperature at . How does the cross sectional area of a wire affect the resistance please don't just give me an equation, what is the explanation please follow 7 . Electrical resistance r of a conductor or wire is where, a is the cross-sectional area of the conductor combining these two laws we get, electrical resistance r of a conductor or wire is where, ρ (rho) is the proportionality constant and known as resistivity or specific resistance of the material of the conductor or wire. I will set up a circuit to find out how length and cross sectional area affect resistance i will need the following components in my circuit to gather all of the necessary results: component holder- so i can change the wire that i am testing voltmeter- measuring potential difference across .

How does the diameter or cross-sectional area of a wire affect its resistance aim: i am going to investigate how the diameter, or gauge , of a wire affects its resistance. A = cross sectional area since r and a are inversely proportional if a (cross sectional area ) is larger then resistance is less so the larger the diameter of the wire the less the resistance. Ib physics investigation: does the cross sectional area of a wire affect it's resistivity research question what are the factors that affect resistance in .

The resistance of a resistor can be calculated when the resistivity of the resistor material and its length and cross-sectional area are known. 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. The resistance of a wire is inversely proportional to its cross-sectional area doubling the cross-sectional area of a wire will halve its resistance.
