## Description

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.
