Resistance is not futile, it is voltage divided by current. A creative simulation presents a wire graphic and allows participants to alter the area, length, and resistivity. As scholars increase or decrease a variable within the resistance formula, the size of the variables displayed in the formula get bigger or smaller based on the relationships in the equation.

Instructional Ideas

• Allow scholars to use an insulation resistance tester during class

Classroom Considerations

• Requires the latest version of Chrome, Firefox, Safari, or Internet Explorer 10+
• Assumes prior knowledge of equations and resistivity

Pros

• Provides a video primer and a document with an overview of the simulation
• Translates into more than 30 languages for students who have a hard time with English

Cons

• None
