Series vs Parallel Resistor Lab

Construct series, parallel, and hybrid resistor networks. Watch animated current markers split at parallel junctions, evaluate equivalent resistance dynamically, and test node voltages with virtual measurement probes.

Series vs Parallel Resistor Lab

Kirchhoff Workbench

Observe voltage division in series, branch current splitting in parallel, and side-by-side comparisons

Mathematical Formulation & Engineering Notes

Series: R_eq = Σ R_i, V_i = V_s · (R_i / R_eq). Parallel: 1/R_eq = Σ (1/R_i), I_i = V_s / R_i.
