	Learning Objective
Circuits Basic DC circuits Passive sign convention Example 1 | (pdf) Example 2 | (pdf)	Consistently label directions of currents and polarity of potential differences in any given circuit (including independent voltage sources and independent current sources, and dependent sources).
Circuits Basic DC circuits Sources: v, i independ, depend Example 1 (pdf)	Use the concepts of both independent and dependent voltage sources and current sources in designing and analyzing circuits.
Circuits Kirchhoff's laws Current sums at nodes | (pdf) Voltage loops | (pdf) Writing v and i eqns Example 1 | (pdf) Example 2 | (pdf)	Apply Kirchhoff's voltage and current laws to obtain equations relating voltages and currents in any given circuit.
Circuits Ohm's law Statement Series resistors Parallel resistors Resistor networks Example 1 (pdf)	Calculate and/or estimate the equivalent resistance (conductance) of a combination of resistances (conductances). Use equivalent resistances (conductances) to reduce circuits.
Circuits KirchHoff's laws Solving circuits Example 1 (pdf) Example 2 (pdf)	Apply Kirchhoff's and Ohm's laws to linear resistive circuits, solve for specified voltages and currents, and design circuits to given specifications, making consistency checks when appropriate. Apply Kirchhoff's and Ohm's laws qualitatively as well as quantitatively.
Circuits v and i dividers Voltage divider Current divider Example (pdf)	Apply voltage divider and current divider relations.
Algebra Simultaneous equations Example (pdf)	Solve linear simultaneous equations.
