Resistance formula is: R = ρL/A Where: ρ: Resistivity constant of the material, in Ω.m L: Length of the wire, in meter A: Cross sectional area of the wire, in m^2 R: Resistance, in ohms (Ω)Metal Resistivity TableMetal Resistivity (Ω . m) at 20 °C Temperature ...
Using theresistance formula: R = (ρ x L) / A R = (1.7 x 10-8ohm-meters x 10 meters) / (2 x 10-6m2) R = (1.7 x 10-7ohm-meters) / (2 x 10-6m2) R = 0.085 ohms Therefore, the resistance of the wire is 0.085 ohms. ...
its material increases with the decrease in the cross-sectional area of the conductor and decreases with an increase in the cross-sectional area. With this, we can conclude that a thin wire has a larger resistance value compared
Step 1: Identify the resistivity (ρ), length (L), and radius (r) of the wire. Step 2: Calculate the cross-sectional area of the wire using the formula for the area of a circle: A=πr2. Step 3: Calculate the resistance (R) of the wire using the formula for resistance: R=...
Our wire resistance calculator uses the following resistance formula: R = ρ× L / A where: R— Resistance in Ω; ρ— Resistivity of material in Ω× m; L— Length of the wire; and A— Cross-sectional area of the wire. You can use this wire resistance calculator to estimate ...
wire and the potential difference applied across the wire. According to him, With the temperature remaining constant, the current flowing through the given metallic wire in an electric circuit is directly proportional to the potential difference across its terminals. Thus, if \(V\) is the ...
