Electric Resistance
The Electrical Resistance Video Tutorial explains the cause and effects of resistance. The variables that affect resistance are described and the mathematical equation relating resistance to those variables is described.
The video lesson answers the following questions:
- What is resistance?
- What variables affect resistance and in what manner do they affect it?

Additional and Related Learning Tools
Concept Builders, Electric Circuits Chapter, Resistance Ranking Tasks
This Concept Builder is focused on the variables affecting resistance. It's great practice and a great follow-up. It might even be great phun.
Minds On Physics, Electric Circuits Module, Mission EC4: Resistance, Voltage, and Current
This Minds On Physics might be a bit pre-mature as the content it covers matches this video and the next video in our Tutorial series. Nonetheless it is worth mentioning and worth (eventually) doing.
Calculator Pad, Electric Circuits Problem Set, Problem #4 and #5
Improve your problem-solving skill with our Calculator Pad. You'll find problems, answers, and audio-guided solutions. Problems #4 and #5 pertain to the use of the Resistance equation from Slide 6.
Physics Classroom Tutorial: Circuits Chapter, Lesson 3: Electrical Resistance
Lesson 3 in our Circuits Chapter of our Tutorial is all about Resistance. The following two pages are the basis of our Video Tutorial. Use them as a reference when needed.
