There's nothing like a good mental challenge. And that' what you'll get with the Equivalent Resistance Interactive. You're given a circuit - series, parallel, or combination - and you must identify the resistance values for the resistors that would be required to create a target equivalent resistance. Click the resistance values into place and check to see if you got it right. If you fail, try, try again. If you're successful, enjoy a star and proceed to the next level. And there's plenty of levels; so plan on having phun for a while.
