Resistance of a Wire Solution

STEP 0: Pre-Calculation Summary
Formula Used
resistance = Resistivity*Length/Cross sectional area
R = ρ*l/A
This formula uses 3 Variables
Variables Used
Resistivity - Resistivity is the measure of how strongly a material opposes the flow of current through them. (Measured in Ohm Meter)
Length - Length is the measurement or extent of something from end to end. (Measured in Meter)
Cross sectional area - 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. (Measured in Square Meter)
STEP 1: Convert Input(s) to Base Unit
Resistivity: 1.7E-05 Ohm Meter --> 1.7E-05 Ohm Meter No Conversion Required
Length: 3 Meter --> 3 Meter No Conversion Required

Resistance of a Wire Formula

resistance = Resistivity*Length/Cross sectional area
R = ρ*l/A

Explain resistance of a wire and factors affecting its properties ?

Resistance wire is wire intended for making electrical resistors (which are used to control the amount of current in a circuit). It is better if the alloy used has a high resistivity since a shorter wire can then be used. In many situations, the stability of the resistor is of primary importance, and thus the alloy's temperature coefficient of resistivity and corrosion resistance plays a large part in material selection. When resistance wire is used for heating elements (in electric heaters, toasters, and the like), high resistivity and oxidation resistance are important. Sometimes resistance wire is insulated by ceramic powder and sheathed in a tube of another alloy. Such heating elements are used in electric ovens and water heaters and specialized forms for cooktops.

How to Calculate Resistance of a Wire?

Resistance of a Wire calculator uses resistance = Resistivity*Length/Cross sectional area to calculate the Resistance, The resistance of a wire is a measure of the opposition to current flow in an electrical circuit.

FAQ

What is Resistance of a Wire?
The resistance of a wire is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω) and is represented as R = ρ*l/A or resistance = Resistivity*Length/Cross sectional area. Resistivity is the measure of how strongly a material opposes the flow of current through them, Length is the measurement or extent of something from end to end 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 of a Wire?
