Lesson 7: How do Ohm's Law and Constraint-Based Reasoning Help in Thinking About Circuits?
This lesson offers a bridge between different conceptual models using Cyclic Simultaneous Causality and algorithms for reasoning about voltage, resistance, and the resulting current. It is designed to help students see the links between resistance, voltage, and current so that the relationship known as Ohm's Law makes sense to them. It involves reasoning from the constraints in the system.
