How to Evaluate Resistance using Losses (STL)?

Resistance using Losses (STL) evaluator uses Resistance = Power Loss/(3*Receiving End Current^2) to evaluate the Resistance, The Resistance using Losses (STL) represents the opposition to current flow due to the line's material properties. In short lines, resistance is typically low due to the line's short length, resulting in minimal voltage drop and power dissipation compared to longer transmission lines. Resistance is denoted by R symbol.
