Fairly handy. Should add capacitance values in series and parallel since the bulk of the coding is already done in the resistance values in series and parallel.

Thanks for the suggestion.
I implemented it in Seafoid 2.0 Final.

ppc (g5, 10.5.2, and g4, 10.4.11)

it works.

It needs some filters (on 4th: none, silver gold; and realist values; why not four color/resistances, plus a filter)

Some confusion when P = U÷I as R = U÷I !
Siince version 0.1, the same aberration.
We wait…

Working fine on my Early-2006 Intel iMac with Mac OS X 10.4.11...

Works good on G5 Dual 1.8GHz PPC Mac.

Clean and simple app & GUI. Could use some input info, for the series-parallel section, though easy enough to figure out by clicking around...

Great beta, great price, and useful tool.

Thanks Dev.!!!

-BTW; I changed it's name to 'PowerCalc', so I can know what is in my >Applications>OtherApps folder.
It had no problem with that...another big plus for this app, and developer!

I don't understand this at all, but the name is squishy and fun to say!
