List of concepts from each lecture in ECE_110 -- this is the Fall 2022 version.
Lecture 1 - 8/29
- Main web page: http://classes.pratt.duke.edu/ECE110F22/
- Circuit terms (Element, Circuit, Path, Branch and Essential Branch, Node and Essential Node, Loop and Mesh).
- Electrical quantities (charge, current, voltage, power)
Lecture 2
- Passive ($$+\rightarrow -$$) Sign Convention and Active ($$-\rightarrow +$$) Sign Convention
- Circuit topology (parallel, series)
- Passive Sign Convention and Active Sign Convention and relation to calculating power absorbed and/or power delivered
- Conservation Laws (conservation of power, Kirchhoff's Voltage Law, Kirchhoff's Current Law):
$$ \begin{align*} \sum_{\mbox{all elements}}\E{p}{abs}&=0 & \sum_{\mbox{closed path}}\E{v}{drop}&=0 & \sum_{\mbox{closed shape}}\E{i}{leaving}&=0 \end{align*} $$
- Accounting:
- The number of independent KVL equations is equal to the number of meshes
- The number of independent KCL equations is equal to the number of nodes minus one
- Example of how to find $$i$$, $$v$$, and $$p_{\mathrm{abs}}$$
- $$i$$-$$v$$ characteristics of various elements (short circuit, open circuit, switch, ideal independent voltage source, ideal independent current source, resistor)
