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:

* 3 Phase NEMA & IEC Negative Sequence Voltage Unbalance
* 3 Phase Power (true power, apparent power, and reactive power)
* Power Factor Correction
* Cost of Use
he easiest, fastest, and most advanced user interface available:
* Use AWG, Metric, and custom conductor sizes (such as defining PCB trace or busbar sizes)
* Create custom conductor materials
* Calculate ANY parameter of most formulas
* Effortlessly scale values from 1 pico- to 1 Tera- ranges
* Unique scale-lock control keeps value displayed in selected range
* Enhanced Clipboard makes your work even easier and faster:
o Cut & Paste full unscaled values
o Direct access with functions assign, add to, subtract from, clear, and invert
* Each formula clearly displayed at the top of each form
* Map functions to any of the hard keys and navigator buttons
* Built-In MiniCalc not only performs all the functions of a common calculator, but also many conversions useful to electrical professionals
Fully compatible with any Palm OS device from system 3 to 6 whether color or monochrome
