Conductor Resistance Calculator







Formula

The formula to calculate the resistance of a conductor is:

\[ R = \frac{\rho \cdot L}{S} \]

What is Conductor Resistance?

Conductor resistance is a measure of how much a conductor opposes the flow of electric current. The resistance depends on the material's resistivity, the length of the conductor, and the cross-sectional area. Different materials have different resistivities, which are often used to design circuits and electrical systems.

Example Calculation

Let's assume the following values:

Step 1: Convert the radius from millimeters to meters:

\[ r = \frac{0.6}{1000} = 0.0006 \text{ meters} \]

Step 2: Calculate the cross-sectional area:

\[ S = \pi \times (0.0006)^2 \approx 1.13 \times 10^{-6} \text{ m}^2 \]

Step 3: Calculate the resistance:

\[ R = \frac{1.7 \times 10^{-2} \times 24}{1.13 \times 10^{-6}} \approx 1.5 \text{ Ω} \]
