I=VRcap I equals the fraction with numerator cap V and denominator cap R end-fraction
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 Electrical Circuit Theory and Technology
As circuits became more complex, we needed better maps. introduced two vital laws to manage "traffic" at circuit junctions: I=VRcap I equals the fraction with numerator cap
): The "pressure" or push provided by a source like a battery. The actual "flow" of electrons through the path. Resistance ( The actual "flow" of electrons through the path
What flows into a point must flow out. No electrons are ever lost.
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.
This simple math allowed engineers to predict exactly how much energy a device would use before even building it. Chapter 3: The Pathfinders
