The notes below are not meant to be comprehensive but rather to capture the general topics of covered during lectures in EGR 224 for Spring 2024. These notes are in no way a replacement for actively attending class.
Lecture 1 - 1/10 - Course Introduction, Nomenclature
- Circuit terms (Element, Circuit, Path, Branch and Essential Branch, Node and Essential Node, Loop and Mesh).
- Accounting:
- # of Elements * 2 = total number of voltages and currents that need to be found using brute force method
- # of Essential Branches = number of possibly-different currents that can be measured
- # of Meshes = number of independent currents in the circuit (or generally Elements - Nodes + 1 for planar and non-planar circuits)
- # of Nodes - 1 = number of independent voltage drops in the circuit
- Electrical quantities (charge, current, voltage, power)
Lecture 2 - 1/12 - Electrical Quantities
- Passive Sign Convention and Active Sign Convention and relation to calculating power absorbed and/or power delivered.
- Power conservation
- Kirchhoff's Laws
- Number of independent KCL equations = nodes-1
- Number of independent KVL equations = meshes
- Example of how to find $$i$$, $$v$$, and $$p_{\mathrm{abs}}$$ using conservation equations and how to check using extra conservation equations
- $$i$$-$$v$$ relationships of various elements (ideal independent voltage source, ideal independent current source, short circuit, open circuit, switch)
- Resistor symbol (and spring symbol)
