It isPractically, when there is an application of a voltage across the conductor, electrons tend to move in a specific direction. This article discusses an overview of the difference between resistance and resistivity.The main difference between these two mainly includes its definitions and its comparison based on different factors.As per the Ohm’s law, we know that V=IR, here R corresponds to the proportionality constant and is termed as Resistance. Both resistance and resistivity describe how difficult it is to make electrical current flow through a material. In this movement, the electrons have a breakdown either with molecules or atoms and generate heat. This lecture is related to Resistivity, how resistance and Resistivity are realted and what is difference between them. In the electrical and electronics industries, the concepts of resistance and resistivity are the most important ones. The lengthier the cylinder, the extra collisions of charges will occur with its atoms.The unit of resistance is measured by ohms, and it is generally represented by Ω at kΩ.

A direct-current resistance between opposing faces of a one-meter cube of the material numerically equates to volume resistivity in SI (Ohm-m). One has to be clear regarding why these topics hold prominence and what are differences and comparison? Different materials have different resistance for the movement of charge in the conductor.The direction of the current is nominated by I sideways with a symbol of the arrow and usually flow with the flow of positive charge and flow opposite to the flow of negative charges. The factors that influence the material’s resistivity is material nature, and temperature and have no dependency on The temperature coefficient of resistivity can be defined as the slight change in the substance resistivity per kelvin and represented as can be represented as:The comparison between these two are discussed below.The resistance is represented as a ratio to length and cross-sectional area of the conductor, while the resistivity corresponds to the ratio conductor’s length to the multiplication of the area of resistance of a conductor.Yes, Resistivity is directly proportional to the complete resistance of the conductor ‘R’.Resistance holds more fundamental property than that of resistivity.No, Resistivity corresponds to entire material property which is also termed as specific resistance.So, these are the foremost differences between resistance and resistivity. Resistance in a conductor is generally the ratio of the potential difference of the current passing through it, while resistivity is usually the ratio of electric field strength to the current density present at a particular temperature. Resistance across a conductor is the ratio of the potential difference across it to the current flowing through it. When a current is flowing over a wire, it looks like water flowing in a water pipe, and when the voltage descent in the wire it is similar to the decrease of pressure that drives water in the pipe.For example, let’s consider a flow of electric current in a uniform piece of cylindrical wire as a result of potential difference. The foremost difference is that resistance opposes the electron flow, while resistivity defines the material’s resistance having the corresponding dimension. But there is a very basic difference between resistance and resistivity. The SI unit of resistance is ohm while the SI unit of resistivity is ( ohmmeter ). It is mathematically written as R = V/I or R = ρ(L/A).Where, l – length of the conductor, a – cross-section area of the conductor, ρ – resistivity of the material. Resistance is always connected to the specific conductor; on the flip side, resistivity is usually linked with the material of the conductor.The term resistance is used in conductors and acts as an obstacle in the flow of current or free electrons that are present in a conductor. The resistivity across a metal wire is directly proportionate to the temperature of the material, and it is independent of the dimensions.Factors affecting resistivity are included as the resistivity of a conductor rises with an increase in its temperature, and the resistivity of a conductor decreases with a decrease in temperature. The formula for resistance is written as R = V/I or R = ρ(L/A); on the flip side, the formula for resistivity is written as ρ = (R×A)/L.The applications of the property of resistance in daily life are used in various places and things like fuses, heaters, sensors, etc. The symbol of resistance is R; on the contrary, the symbol of resistivity is ρ.Resistance is considered as a property of a specific object and be determined by the temperature, object’s material, along with its dimensions (directly proportionate to length, inversely related to the cross-sectional part in a constant metal wire); on the other hand, resistivity is usually a property of a specific material, and it is independent on the dimensions, but it is, though, reliant on temperature and the material of the conductor. Resistivity is measured in ohm-meter and represented as (Ωm). So, here is a detailed view of all these topics. What is the difference between Resistance and Resistor? The new resistance will become. Why would we want to do that? The main difference between resistance and resistivity is that resistance opposes the flow of current and free electrons, whereas the resistivity describes the resistance of the specific material having a particular dimension. Some applications of resistivity are used in calcareous soil and a quality control test.The above discussion concludes that the resistance opposes the flow of current and free electrons and it is directly dependent on the dimension and cross-section of area or length, whereas the resistivity is the resistance of the specific material having a particular dimension but independent of the dimension, reliant on temperature.Harlon currently works as a quality moderator and content writer for Difference Wiki.
