Resistance(Single-Phase Three-Wire OS) Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Resistance Overhead AC - (Measured in Ohm) - Resistance Overhead AC 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 Overhead AC Wire - (Measured in Meter) - Length of Overhead AC Wire is the total length of the wire from one end to other end.
Area of Overhead AC Wire - (Measured in Square Meter) - Area of Overhead AC Wire is defined as the cross-sectional area of the wire of an AC 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 Overhead AC Wire: 10.63 Meter --> 10.63 Meter No Conversion Required
Area of Overhead AC Wire: 0.79 Square Meter --> 0.79 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = (ρ*L)/A --> (1.7E-05*10.63)/0.79

Evaluating ... ...

R = 0.000228746835443038
