The length of a nichrome wire affects its resistance essay

The length of a wire and its effect on resistance papershow does the affect resistance resistance resistivity first, the total length of wires will affect amount resistance. The resistance of any wire has been shown to be directly proportional to the length of the wire and inversely proportional to the wire's cross-sectional area the constant of proportionality in this equation is called the material's resistivity and is measured in ohm-meters. To investigate the effect of changing the length and thickness of nichrome wire on its resistance documents similar to prac 8 resistance and heat - using nichrome wire industrialtuff csa tray cables uploaded by prograde awg to metric conversion chart.

the length of a nichrome wire affects its resistance essay The 4 different variables that affect the resistance of a wire are: 㘠length of the wire 㘠area of cross-section of the wire 㘠material of the wire 㘠heat in every circuit there is a current, i, a voltage, v, and a resistance, r.

For a resistor whose cross sectional area does not vary significantly, its resistance, r, can be calculated as follows: [1] r = ρl/a measure or use a given value for the length of a piece of wire repeat steps 5 through 13 for your highest resistance nichrome wire when calculating alpha, do not use any data obtained in the room. 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.

Nichrome (nicr, nickel-chrome, chrome-nickel, etc) is any of various alloys of nickel, chromium, and often iron (and possibly other elements)the most common usage is as resistance wire, although they are also used in some dental restorations (fillings) and in a few other applications. Resistivity of nichrome depends on temperature please refer nichrome wire data tables which are standard and available from many sources and websites. 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 in my main investigation i will see if this observation applies to my results.

Why nichrome wire we have chosen nichrome wire because it is able to produce a large resistance even with a relatively small area and is easily measurable, whereas suppose if we use copper wire then we will need a substantially large amount of wire for us to be able to measure the resistance. Resistance and resistivity openstaxcollege learn about the physics of resistance in a wire change its resistivity, length, and area to see how they affect the wire’s resistance the sizes of the symbols in the equation change along with the diagram of a wire. If a wire of resistance is stretched to 5 times to its original length, what will be the effect on current through wire what is the effect of moisture on a nichrome wire what is the ratio of resistance of two wires having the same length, but the diameter of the first wire is just double that of the second wire.
