How is resistance calculated ?

The property of a substance by virtue of which it opposes the flow of electric current through it is called electrical resistance. Its formula is R= (ρ*i )/ A where R is the resistance measured in ohms, ρ is the resistivity measured in ohm-meter , l is the length of the conductor, measured in metres (m), A is the cross-sectional area of the conductor measured in square metres .

How to Calculate Resistance?

Resistance calculator uses Resistance=(Resistivity*Length of Conductor)/Cross sectional area to calculate the Resistance, Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance and 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) and Cross sectional area (A) and hit the calculate button. Here is how the Resistance calculation can be explained with given input values -> 1.700E-5 = (1.7E-05*10)/10.

FAQ

What is Resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit and is represented as R=( ρ*l)/A or Resistance=(Resistivity*Length of Conductor)/Cross sectional area. Resistivity is the measure of how strongly a material opposes the flow of current through them, Length of Conductor is the measure of length of wire and Cross sectional area is the area of a two-dimensional shape that is obtained when a three dimensional shape is sliced perpendicular to some specifies axis at a point.
How to calculate Resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit is calculated using Resistance=(Resistivity*Length of Conductor)/Cross sectional area. To calculate Resistance, you need Resistivity ( ρ), Length of Conductor (l) and Cross sectional area (A). With our tool, you need to enter the respective value for Resistivity, Length of Conductor and Cross sectional area and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
