The Complete Beginners Guide to Arduino - 2021 - Basic Electric Theory

The video tutorial introduces the fundamental concepts of electricity, focusing on three key units: voltage, current, and resistance. It uses a water analogy to explain how electric current flows, measured in amperes, and how voltage acts as the pushing force that drives this flow. The relationship between voltage and current is highlighted, showing that increasing voltage results in increased current. Resistance is introduced as a factor that restricts current flow, akin to narrowing a pipe in the water analogy. The tutorial sets the stage for deeper exploration of these concepts in future lessons.
