Section 21.4 Voltage Diagrams
In a previous section, in
Voltage Sketch, you made a sketch of voltage as a function of time for a charge moving around a circuit. The video below provides a more formal representation for this idea.
Voltage diagrams are very useful representations to draw when analyzing circuits. They can be as useful as free-body diagrams!
Representation 21.4.1. Voltage Diagrams.
A voltage diagram shows how the voltage changes throughout a circuit. Typically, a voltage diagram starts at zero and will utilize an arrow to show how the voltage is increasing or decreasing across certain elements. The Loop Rule (
The Loop Rule) is often used in tandem with voltage diagrams.
