Circuit analysis and power quality reference — Ohm's law, resistor networks, and power factor with real UK reactive-charge context.
Ohm's law solver — voltage, current, resistance and power from any two — plus series and parallel resistor networks.
4-band decode and encode — pick colours for ohms, or type a resistance for the nearest standard bands. IEC 60062.
Power triangle solver, UK-focused quick-select operating points, capacitor correction sizing, and a UK DNO reactive-charge estimator.
Turns ratio solver with directly modifiable, visually-exact coil turns, plus a sourced efficiency-vs-load model.
Six to eight times running current before the shaft moves — and what star-delta, soft starters and drives really cost you in torque.
What a bank really delivers once depth of discharge, the Peukert effect and inverter losses have all taken their cut — which is never the number on the label.
The right AWG for your current and distance, and the actual voltage drop — real NEC ampacity and resistance tables.
