Electrical

Estimate EV charging time online from battery size, SOC targets, charger limits, taper, cost, and added range to plan home charging or trip stops.

Calculate online series RLC impedance from resistance, reactance, or component values to check magnitude, phase, power factor, and current behavior.

Calculate PoE switch capacity from device rows, IEEE power basis, cable loss, reserve targets, port demand, boot surge, and shedding cues before rollout.

Calculate power factor from kW and kVA, then estimate reactive kVAR, phase angle, correction kVAR, kVA reduction, and capacitor sizing before field review.

Calculate rack power density from device watts, rack U, feed models, circuit load limits, growth factors, and heat output to check headroom before deployment.

Calculate transformer turns ratio, secondary turns, RMS load currents, efficiency input VA, design margin, and turn-check warnings before winding review.

Calculate UPS runtime from W or VA load, battery energy, efficiency, battery health, reserve, derating, and readiness checks for shutdown planning.

Calculate AWG wire gauge from current, one-way run, voltage, drop limit, material, and temperature column with ampacity checks and voltage-drop charting.
