Resistance of a wire

This app can quickly compute electrical properties of a specific wire - its resistance. Resistance describes how strongly a given cable opposes the flow of an electric current, and conductance measures a wire's ability to conduct it.So this app is a very good solution for the electricians and engineers.
You can select wire and can measure the power of transmission line through this app.You can also measure the Area And length relationship with wire.Nowadays, one of the most frequently used conductors is copper which can be found almost in every electrical device. Read on if you want to find out what are resistivity of copper, and what rere the remittances.Resistivity ρ, unlike resistance, is an intrinsic property of a material. It means that it doesn't matter whether the wire is thick or thin, long or short. The resistivity will always be the same for a specific material, and the resistivity units are "ohm meter" (Ω * m). The higher the resistivity is, the more difficult it is for the current to flow through a wire. You can check our drift velocity calculator to find out how fast is electricity.

Ohm’s law describes the fundamental way in which electrical circuits behave. There is a direct relationship between current, resistance and voltage. Ohm’s law also states that resistance is a constant independent of both current and voltage.Both conductance and resistance depend on the geometrical dimensions of a wire. Our wire resistance calculator uses the following resistance formula:

R = ρ * L / A

where

R is the resistance in Ω,
ρ is the resistivity of material in Ω * m,
L is the length of wire,
