Electrist - For figuring everything from Ohm's Law to VSWR, nothing else even comes close. Try the free trial of Electrist and see why electronic engineers in some of the finest R&D laboratories in the world, industrial maintenance crews, power utilities, RF & audio engineers, circuit designers, telecom engineers, Ham operators, electronics hobbyists, and fanatical Do-It-Yourselfers - among others - love this software. With a user interface, features, and formulas found in no other software backed up with world-class customer service, it's no wonder!
Even though it's the finest formula calculator by a long shot, it's even more than that. Electrist does seamless NEC ampacity look-ups to automatically give you the correct wire and cable sizes for any application - in both the AWG and Metric standards. You can also input any conductor's size, length, and material properties - from PCB traces to busbars - and accurately find the voltage drop.
Sizing panels & transformers is also a snap with the built in load calculator. Enter any number & configuration of delta or wye/star and 3 phase, line-to-line, line-to-neutral, and/or centertap-to-neutral to instantly get both the phase and line loading in current, true power, and apparent power. The most complete set of calculations - hundreds of formulas & variations:
