Three-phase power delivers energy on three conductors carrying sinusoids 120° apart, so total power is constant and motors self-start. Line and phase voltages differ by √3, and real power is P = √3·V_line·I·cosφ. The power factor cosφ measures how much current actually does useful work.

Dijkstra's algorithm finds the shortest path from a source (A, blue) to every other node in a weighted graph, always expanding the closest unvisited node next. The number inside each node is its shortest distance from A; the green edges trace the optimal route to your chosen destination. It powers GPS routing, network protocols, and logistics. Click any node to re-target.
