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 ...
where ρ is known as theresistivityconstant or thecoefficient of resistance. It is also known as the specific resistance of the material. Its units are Ohm-meter. Thus, knowing the length, cross-sectional area and material of the wire, it can be calculated. Silver is the best conductor but...

If a wire is stretched to double its length, what will its new resistance be?Question:If a wire is stretched to double its length, what will its new resistance be?Resistance:It is defined as the property of a material to show hindrance against the current flowing in the...
Resistance is a fundamental concept in physics that quantifies the opposition encountered by an electric current flowing through a conductor. It is denoted by the symbol "R" and is measured in ohms (Ω). The resistance of a conductor depends on its mater
Average Unit Curve Resistance of Train Letting LT be the length of train (m), and the mass of train are uniformly distributed along train, q is the unit mass per meter of train in tons per meter, therefore: If LT ≤ LC, the whole train will be influenced by curve resistance, the tot...
