Why do pipes represent wires?

Pipes represent wires in diagrams and analogies because both systems facilitate the flow of a substance—pipes for liquids and gases, and wires for electrical currents. Just as pipes can have varying diameters and materials affecting flow rate and resistance, wires have different gauges and compositions that influence electrical conductivity and resistance. This analogy helps simplify complex concepts in fluid dynamics and electrical engineering, making it easier to understand the behavior of these systems.
