What a lot of people don't realize is that the foundation for understanding the NEC rules for electrical installations is electrical theory! Whether you're a first-year apprentice still struggling to understand the difference between a volt or ampere, or a veteran electrician trying to sharpen your troubleshooting skills, this product has something for you.

We're sharing this clip from the program to introduce you to the importance of this topic. Please feel free to share this with your friends and co-workers, and for more videos and content on this topic, check out our Electrical Theory Video Library that includes the full program and digital textbook.

In 1831, Michael Faraday discovered that moving a magnet inside a coil of wire caused electrons in the wire to flow in a specific direction. This discovery is the concept used to make alternating-current electricity. To better understand the theory behind how alternating-current is produced, read the attached text and watch this video, where Mike and the team explain this topic in detail.
