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...

No. It's too easy and simple to make it worthwhile writing a stand

alone Ohm's Law program for a PC. There are plenty for IOS and

Android devices, but not for PC's. It might be helpful in finding

something if you were more specific as to what you mean by "other

electronics math"?

I think you'll find one of these to be more suitable:

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?

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.

Basic Ohm's Law calculations can be done on a pocket calculator without

the need for anything more complicated. The biggest pitfall is knowing

*which* voltage or *which* current is actually applied to a particular

resistor, especially if there are several in some sort of array.; it is

not always obvious.

The logic of real-life circuit problems is not particularly amenable to

being sorted out by software.

Go to < www.cq-amateur-radio.com/cq_ham_calc/cq_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.

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

It is simply the application of the Ohm-low :

sigma(I)=0 at a node.

sigma(V)=0 along a loop.

And , of course V=Z*I.

Well, I lied. I found some Windoze and Java programs that do Ohm's

law:

Ohm's Law is under the "other" tab.

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.
