Electric Circuits

DC Circuit Builder

Created by our friends at Nerd Island Studios, the DC Circuit Builder equips the learner with a virtual electronic circuit board. Add resistors, light bulbs, wires and ammeters to build a circuit, Explore Ohm's law. Compare and contrast series, parallel and combination circuits. Use a voltmeter to measure voltage drops. Do all this without the fear of being electrocuted (as long as you don't use your computing device in the bath tub). The Physics Classroom has prepared four different activity sheets to accompany DC Circuit Builder. 

Now available with four Concept Checkers.


Equivalent Resistance

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.

Now available with Task Tracker compatibility. Learn more.



Know Your Potential

Every Physics student should know their potential - their electric potential. With this interactive Concept Builder, all physics students can understand the changes in electric potential that occur as charge passes around a circuit. Consisting of three activities - Color Those Wires!, Which Bulbs Light?, and Volt On It!, this skill-building activity will help you uncover an understanding of electric potential that you never knew you could attain. Get started on this Know Your Potential Concept Builder and discover that potential today.

Note: As of August, 2017 the Know Your Potential activity has been moved to our Concept Builders section.
