Ck 12: Ohm's Law
[Free Registration/Login may be required to access all resource tools.] For this lesson, students learn about the invention of the battery and how a battery works, and about resistance in an electrical circuit. As well, Ohm's Law is used...
University of Colorado
University of Colorado: Ph Et Interactive Simulations: Ohm's Law
Manipulate the voltage and resistance for a simple circuit to see how these affect the amount of current. The symbols in the Ohm's Law equation grow bigger and smaller to emphasize the changes.
Khan Academy
Khan Academy: Resistors in Series and Parallel Review
Review how to find the equivalent resistance for resistors in parallel and series configurations. Recall the current and voltage properties of series and parallel configurations of resistors.
