1. What is Constant Using Resistance (1-Phase 2-Wire US)?

Constant Underground AC is defined as the constant of line of an Overhead supply system. It represents a calculated value used in electrical engineering to characterize the properties of underground AC transmission lines.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ K = \frac{4 \times P \times L \times R \times A}{P_{loss} \times (V_m)^2} \]

Where:

\( K \) — Constant Underground AC
\( P \) — Power Transmitted (Watt)
\( L \) — Length of Underground AC Wire (Meter)
\( R \) — Resistance Underground AC (Ohm)
\( A \) — Area of Underground AC Wire (m²)
\( P_{loss} \) — Line Losses (Watt)
\( V_m \) — Maximum Voltage Underground AC (Volt)

Explanation: This formula calculates the constant value based on the physical and electrical properties of the underground AC transmission system.
