Software to calculate Ohms Law and other electronics math
Is there any Software to calculate Ohms Law and other electronics math?
I have never been good at Mathematics, once you put numbers over other numbers, use alphabet letters in place of numbers, or talk about squaring a number, I am completely lost. This is nothing new. Even in high school I needed special help and barely passed algebra. Yet, I have worked with electronics all my life. (55+ years). I usually fInd the correct resistors by trial and error, using pots and decade boxes. Or using meters for watts, amps, or volts. Most of the time I see someone in a youtube video using this kind of math, I skip the video. I just hate math and always will. But I'd welcome a piece of software that would calculate simple ohms law things like determining the resisitor size or amperage, etc. Yes, I'm aware of websites that do that math, but I do not have internet access in my shop, which is where I need this sort of thing. Is there any software (preferably free) that I can put on my laptop PC to do this? (Must be suitable for Windows XP SP3 Pro). Google did not find anything except those online (web based) calculators... |

There is the old PIRE wheel, or is that too simple for the OP? Of course then you need to use either your head or a calculator - I mean really, I=E/R, how hard is that? John :-#)# |
Software to calculate Ohms Law and other electronics math
Web-based software is useful to calculate parallel resistors and such-like. There was a discussion in another group about how to hot-switch between two amplifiers, neither of which would like to be unloaded (but for different reasons).
Turned out that a parallel high-wattage resistor across the amp outputs would do the trick, after a bit of calculation. Using a web-based calculator greatly sped up the process. http://www.1728.org/resistrs.htm Peter Wieck Melrose Park, PA |

Go to http://www.cq-amateur-radio.com/cq_h..._ham_calc.html and download HAM-CALC ( HCALC_129.zip ). I unzip the file into a ram-disk whenever I need to use the program. Since it uses GWBASIC, you need to type "cmd" in the START - Run.. box. I see that you are using WinXP, so this isn't a problem. For more recent version of Windows, you would have to install DOSBOX first. David --- Adrian Tuddenham wrote: wrote: Is there any Software to calculate Ohms Law and other electronics math?

Ohms law, capacitor reactance, numerous other things are frequently resolved with simple software. And I won't mention spice or its limitations. |

You would be better off with a piece of log/log graph paper, labeled for a convenient range of V on one axis, and I on the other axis. Every resistor value can be represented by a straight line (a diagonal) on the graph. Scribe in 1 ohm, 10, 100, 1000, 10k etc. lines, and glance at it when you want a value. Calculators are slow. Laminated charts inform in a couple of seconds, and can be taped on any convenient door/partition/refrigerator. |
