TrueOhm is a fast, free electrical calculator built for electricians, apprentices, and engineers. Five powerful calculators in one app: • Ohm's Law Wheel — Enter any two of voltage, current, resistance, or power and instantly solve the other two. • AC Power — Calculate real power, apparent power, current, and voltage for single-phase and three-phase systems. • Power Triangle — Solve the relationship between kW, kVAR, kVA, power factor, and phase angle. • Energy Cost — Estimate energy consumption and cost for any load over any run time. • Efficiency — Calculate motor or system efficiency from input and output power. Every calculation shows its work — tap "How this was calculated" to see the exact formulas and substitutions used. Built-in sanity checks warn you about impossible values without blocking your workflow. Designed for the field. No ads. No subscriptions. Just fast, accurate calculations from 509 Electric.
