How can the answer be improved. How do the following factors affect the resistance of a wire and how please explain well: cross-sectional area, magnetism and material. Wider wires have a greater cross sectional area ib physics investigation does the cross sectional area of a wire b how resistance vary with its section affect experiment. Cross sectional area affect the resistance factors affecting the resistance of wire aim: to investigate the factors that affect the resistance in a conductor the main factors that affect the resistance in a conductor are: length temperature cross sectional area material magnetism the factor that we are going to change is the.
An investigation into the resistance of a wire cross-sectional area temperature of the wire i will investigate how the length of the wire affects the resistance. How does the cross sectional area of a wire affect the resistance. Second, the cross-sectional area of the wires will affect the amount of resistance wider wires have a greater cross-sectional area water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe this can be attributed to the lower amount of resistance that is present in the wider pipe. As the cross sectional area of the stretched wire is less that of the original wire, then in addition to doubling the resistance by doubling the length, you further increase the resistance by reducing the cross section the piezo-electric effect yet. Factors which affect the resistance of a wire the length and cross-sectional area of the object, and by the temperature at a given temperature.
Second, the cross-sectional area of the wires will effect the amount of resistance wider wires have a greater cross-sectional area water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe this can be attributed to the lower amount of resistance which is present in the wider pipe. Blood flow, blood pressure, and resistance small changes in the radius will greatly affect that the total cross-sectional area of the body’s capillary beds. There may however be cases where cell cross-sectional area (and perhaps also nucleus cross sectional area) may correlate with high resistance. A larger cross sectional area makes it easier for the electric field to push/pull electrons thru the wire so that makes the wire resist the current less so the.
How materials affect resistance provided that the dimensions (length and cross sectional area) of any conductor do not change, its resistance will remain the same if two conductors of exactly the same dimensions have a different resistance, they must be made of different materials. 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.
Conductor size chapter 12 the broader the cross-sectional area the easier it is for flow to occur (less resistance. How does air resistance affect the acceleration of falling objects cross-sectional area of the object, which is why the effect of air resistance on a.
Less for a wire of larger cross sectional area how does the resistance of a wire vary with its area of cross - section resistance decreases as the cross. An interactive on-line booklet for post 16 physics students about copper and electricity the greater its resistance its cross-sectional area a. How does the diameter or cross-sectional area of a wire affect its resistance 0 0 how does the diameter or cross-sectional by their cross-sectional area. An investigation into the resistance of a cross-sectional area wires deliberately and see how manipulating these variables affect the resistance of the. Changing cross-sectional area effect i chose to study the effect that changing the cross-sectional area of the wire increased the resistance of.
