Electric Circuits

This simulation applies Ohm’s law, V = IR, and the standard series/parallel resistor-combination rules (R_series = R₁ + R₂ + …; 1/R_parallel = 1/R₁ + 1/R₂ + …) to a simplified DC circuit of an ideal voltage source and up to eight ideal resistors — the standard equations found in any introductory electronics text, computed by `@scienceverse/simulations-core`’s real, tested `circuits` model, not an approximation invented for this page.

Supply voltage, each resistor’s resistance, the resistor count (one to eight), and the topology (series or parallel) are each adjustable within a scientifically valid range. Every recomputation runs in a dedicated Web Worker, off the page’s main thread, and the animated circuit diagram shows real current flow — every point on a series loop moves at one shared speed (series current is identical everywhere), while each parallel branch moves at its own independent speed (parallel current divides across branches). A shareable link captures the exact current parameters. Readers whose browser cannot run canvas rendering, who prefer reduced motion, or who have JavaScript disabled see the real solved current, voltage and power for every resistor below instead, in an accessible data table.
