Resistance(DC 3-Wire) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Resistance Overhead DC = Resistivity*Length of Wire DC/Area of Overhead DC Wire
R = ρ*L/A
This formula uses 4 Variables

Variables Used

Resistance Overhead DC - (Measured in Ohm) - Resistance Overhead DC is defined as the property of the wire or line that opposes the flow of current through it.
Resistivity - (Measured in Ohm Meter) - Resistivity is the measure of how strongly a material opposes the flow of current through them.
Length of Wire DC - (Measured in Meter) - Length of Wire DC is the total length of the wire from one end to other end.
Area of Overhead DC Wire - (Measured in Square Meter) - Area of Overhead DC Wire is defined as the cross-sectional area of the wire of an overhead DC supply system.

STEP 1: Convert Input(s) to Base Unit

Resistivity: 1.7E-05 Ohm Meter --> 1.7E-05 Ohm Meter No Conversion Required
Length of Wire DC: 12.7 Meter --> 12.7 Meter No Conversion Required
Area of Overhead DC Wire: 0.65 Square Meter --> 0.65 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = ρ*L/A --> 1.7E-05*12.7/0.65

Evaluating ... ...

R = 0.000332153846153846
