Long-distance power transmission
Line loss P_loss=I²R=(P/U)²R; raising U cuts I=P/U so loss ∝ 1/U².

FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Long-distance power transmission” lab practice?
Tune parameters and match readouts to the “Long-distance power transmission” relations — useful for prep and demos.
How do I connect meters?
Ammeter in series; voltmeter in parallel — watch polarity and range.
When does Ohm’s law apply?
For ohmic conductors I=U/R; nonlinear devices need their own curves.
