Some students have problems visualizing the application of Ohm’s Law and the equations for voltage, current, resistance, and power. If you work best with visuals, or if you’d just like a place to check your work*, take a look at the Ohm’s Law Calculators available at http://www.the12volt.com/ohm/page2.asp.

*The use of these tools to get homework and practice answers will not help make you smarter or promote understanding! Do your own work first!

Here’s a cool tool for checking that large number multiplication or division. Its a MS Excel spreadsheet set up to do either multiplication or division. I don’t, of course, advocate the use of this tool instead of working the problem yourself, but its a good way to check your work.

This MS Excel spreadsheet should work fine with open source alternatives that can open and edit .xls files, including OpenOffice.org and Gnumeric.

Just click on the screenshot below to download the spreadsheet in .zip format, ready to decompress and use!
