Analogi air pada rangkaian listrik
This simulation runs a water circuit alongside an electric one so you can see which parts correspond. Pumps stand in for cells, narrow pipes for resistors, and the flow rate for current, giving you a physical picture to fall back on when the equations get abstract.
Cara memakai simulasi ini
- Change the pump strength and the pipe widths
- Rearrange components into series and parallel layouts
- Compare the water flow with the current reading
Yang perlu diamati
- Flow rate is identical all round a single loop, just as current is
- Most of the pressure drop occurs across the narrowest pipe
- Adding a parallel branch increases total flow, mirroring reduced resistance
Fisika di baliknya
Potential difference plays the role of pressure difference, current the role of volumetric flow, and resistance the role of pipe constriction, giving Ohm's law V = IR. The analogy correctly predicts that current is the same all the way round a series loop — water is not used up by a narrow pipe, and charge is not used up by a resistor.
