What is resistance?

Resistance is the measure of how much a material opposes the flow of electric current. It determines how much the current is reduced as it passes through a component or conductor. Resistance is influenced by the material, length, and cross-sectional area of the conductor.

How to Calculate Resistance?

Resistance calculator uses Electric Resistance = (Resistivity*Length of Conductor)/Cross-Sectional Area to calculate the Electric Resistance, Resistance formula is defined as a measure of the opposition to current flow in an electrical circuit, which depends on the material of the conductor, its length, and its cross-sectional area, and is a fundamental property in understanding the behavior of electric circuits. Electric Resistance is denoted by R symbol.

How to calculate Resistance using this online calculator? To use this online calculator for Resistance, enter Resistivity (ρ), Length of Conductor (L_conductor) & Cross-Sectional Area (A) and hit the calculate button. Here is how the Resistance calculation can be explained with given input values -> 38.57143 = (0.0006*0.35)/1.4E-05.

FAQ

What is Resistance?

Resistance formula is defined as a measure of the opposition to current flow in an electrical circuit, which depends on the material of the conductor, its length, and its cross-sectional area, and is a fundamental property in understanding the behavior of electric circuits and is represented as R = (ρ*L_conductor)/A or Electric Resistance = (Resistivity*Length of Conductor)/Cross-Sectional Area. Resistivity is the opposition to the flow of electric current in a conductor, measured by the degree to which it resists the flow of electric charge, Length of Conductor is the distance between the two ends of a conductor through which electric current flows & Cross-Sectional Area is the area of a given cross-section of a conductor, which affects the flow of electric current through it.

How to calculate Resistance?

Resistance formula is defined as a measure of the opposition to current flow in an electrical circuit, which depends on the material of the conductor, its length, and its cross-sectional area, and is a fundamental property in understanding the behavior of electric circuits is calculated using Electric Resistance = (Resistivity*Length of Conductor)/Cross-Sectional Area. To calculate Resistance, you need Resistivity (ρ), Length of Conductor (L_conductor) & Cross-Sectional Area (A). With our tool, you need to enter the respective value for Resistivity, Length of Conductor & Cross-Sectional Area and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Electric Resistance?

In this formula, Electric Resistance uses Resistivity, Length of Conductor & Cross-Sectional Area. We can use 3 other way(s) to calculate the same, which is/are as follows -

Electric Resistance = Resistivity*Wire Length/Cross-Sectional Area of Wire
Electric Resistance = (Final Resistance*Wire Length^2)/((Final Length of Wire)^2)
Electric Resistance = Resistance at Reference Temperature*(1+Temperature Coefficient of Resistance*Change in Temperature)
