# resistance calculator

Hey, I am making a SIMPLE parallel/series resistance calculator and wondered
if anyone wanted to test it...

I'm sorry but it is programmed in VB.net and I might switch it to C/C++
someday but for now it is going to require the .NET framework. Anyway, if
you want to try it let me know what you want added. The next step I was
going to do is show the voltage dropoff of each resistor. Oh well... Let me
know what you think.

Not half bad.. here are some suggestions..

1) ad a power of ten (ie 330e3 = 330,000) button
2) make hotkeys for clear and calculate buttons
3) add a thing to do caps in paralell and series.. just gotta flip the
formulas from the resistors.. While your at it do inductors
4) maybe add a keypad looking thing like when you use the windows
calcuator.. Either that or scale down the GUI, there is a lot of empty
space.

The math seemed alright tho.. i tryed out a few calculations and it came
up right every time..

Hope my comments helped! i'm not very experienced using C++ or i'd
probabally just write out code for what i thought needed fixing.. seems
like your on your way to an alright program tho..

good luck

Good thought...
Another good thought...
Was just thinking about that...
Never thought about that....
Yeah, I should, I just never liked the GUI keyboard but I see your point.
Yeah, I knew that was coming. I left it big for my future add-ons.
Yeah, I am only using the reciprical of the sum of recipricals to keep the
logic down, and there isn't a lot of ways I can screw that one up. It has
worked on all of my tests and there is a limit on the number of resistors to
avoid wrapping the value and giving false results.
Thanks!

It's actually Visual BASIC.NET. I do program in C/C++ and JAVA though. This
was just a little app to get me into the .NET framework. Not sure that I
like .NET but it isn't that bad....
