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
As circuits became more complex, we needed better maps. introduced two vital laws to manage "traffic" at circuit junctions: Electrical Circuit Theory and Technology
): The "pressure" or push provided by a source like a battery. The actual "flow" of electrons through the path. Resistance ( The energy "pushed" into a loop by a
I=VRcap I equals the fraction with numerator cap V and denominator cap R end-fraction The actual "flow" of electrons through the path
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.
): The "friction" or obstacles that slow the flow down, like a lightbulb or a heater. Chapter 2: The Law of the Land
