Someone in another forum suggested this:

http://www.electronics2000.co.uk/

"Whatever your interest in electronics, you'll find something here for you - a beginners guide to project building, technical data including connector and component pin-outs, online interactive formulae calculators, software downloads including Electronics Assistant and EPE Index (see screenshots below), links to other sites and more."-Ibid

You don't have to download anything because you can use the calculators in this link:

Capacitance Unit Converter
Capacitor Charge / Energy Calculator
Capacitor Code Calculator
Inductor Code Calculator - Colours to Value
Inductor Code Calculator - Value to Colours
L / C Reactance Calculator
LED Series Resistor Calculator
Ohms Law Calculator
Potential Divider Calculator
Power (Wattage) Calculator
Series / Parallel Capacitor Calculator
Series / Parallel Resistor Calculator
Wheatstone Bridge Calculator
Resistor Colour Code Calculator

    This is indeed very useful calculators/link, I have already bookmarked the page.
    Thank you for the link.

    The Voltage Divider Calculator is giving me some unrealistic results.

    Try entering 50K for R1 and 1K for R2 @ 5 volts. The output is not believable.

    I get the right answer: 98.039mV.

    Oh, that's hilarious.

    That little m in "V2 = 98.039m Volts" changes everything.

    All I saw was "Volts".

    To be honest, that's all I saw, too, at first. I was thinking, "Whoa! It's a miracle!" But the "m" caught my eye before I headed out to the shop to build that extraordinary device. :)

    Dang it... it's those guys again with their silly laws of physics!!! Stupid Ohm. If it wasn't for them, we'd have perpetual motion machines and all kinds of other fun stuff!

    Well, YEAH! Everybody knows that you can t get more voltage out of a voltage divider than you put in. To do that, you have to reverse the divider circuit to make it a voltage multiplier:

    Very impressive voltage multiplier. I always thought you needed diodes, capacitors, and a pulse for that.

    The FREE NEETS manuals are always a useful addition - not exactly software, but PDF files of a self-study course.

    And in Ubuntu Linux, there is a whole section of downloads for electronics and HAM radio software.
