The Formula Explained
Voltage Drop: \( V_{drop} = I \cdot Z \cdot L \)
Power Loss: \( P_{loss} = I^2 \cdot Z \cdot L \)
Glossary of Terms
- Input Voltage (V): The initial voltage supplied to the transmission line.
- Line Impedance (Ω): The resistance and reactance of the line, affecting the overall transmission efficiency.
- Line Length (km): The physical length of the transmission line.
How It Works: A Step-by-Step Example
Consider a transmission line with an input voltage of 120V, line impedance of 50Ω, and a length of 10km. Using the formulas above, you can compute the voltage drop and power loss across the line.
Frequently Asked Questions (FAQ)
What is a transmission line?
A transmission line is a specialized cable or other structure designed to conduct alternating current and radio frequency signals.
How is line impedance calculated?
Line impedance is calculated based on the physical characteristics of the line and the frequency of the signal being transmitted.
