): The "friction" or obstacles that slow the flow down, like a lightbulb or a heater. Chapter 2: The Law of the Land

This simple math allowed engineers to predict exactly how much energy a device would use before even building it. Chapter 3: The Pathfinders Electrical Circuit Theory and Technology

I=VRcap I equals the fraction with numerator cap V and denominator cap R end-fraction ): The "friction" or obstacles that slow the

The energy "pushed" into a loop by a battery must be completely "used up" by the components in that loop. Chapter 4: From Theory to Technology and something to drive.

Imagine electricity not as a mysterious spark, but as a river. For a river to flow and do work—like turning a waterwheel—it needs three things: a push, a path, and something to drive.
