Visual tools for exploring how circuits behave — drag sliders, watch the values change.
V = I × R. Drag any two, watch the third derive itself. See current, voltage, and power update in real time.
LiveCopper vs aluminum, 120V through 600V, single- and three-phase. Slide the length and see voltage decay to the load.
LiveRotating phasors + live sinusoids. Toggle wye vs delta and watch V_line = √3 × V_phase come out of the geometry.
Build a circuit, add resistors in series or parallel, watch total resistance and branch currents recompute.
LiveAdd resistive and inductive load, see real vs reactive vs apparent power, and correct with a capacitor bank.
LivePrimary/secondary turns, step-up vs step-down, see impedance reflection and current transformation.
LiveDOL vs star-delta vs soft-start vs VFD — watch inrush current profiles compare on the same graph.
Click slots to assign breakers, balance the phases, check demand loads against the main breaker.
LivePoint-to-point fault calculation with transformer contribution and cable impedance.
LiveIncident energy calculator with PPE category output per NFPA 70E / CSA Z462.
