This clip is just a few minutes of a multi-hour course.  

Master this subject with our full length step-by-step lessons!

Lesson Summary:
Learn the definition of Current and Voltage and how they apply to Circuit Analysis.  Many students confuse the concepts associated with Current and Voltage, and it is critical that all students have a solid foundation of this knowledge before studying more advanced topics in the course.

First, we describe what Current is, why it is important, and the unit of Amperes.  Next, we explain what Voltage, how it relates to current, and the unit of the Volt.  

Finally, we tie it all together with examples to give the student confidence with these topics.
