Introduction to Electricity



Understanding the key electrical concepts of charge, current, potential difference and resistance is critical to understanding the entire topic of electricity.  In this video, in addition to explaining these concepts in clear language, we’ll get some practice in using two key equations, and will cover material which is relevant to the first of the electricity required practical activities.

Key Words
