8.
Be able to explain the differences between an electrical device and a circuit element.

9.
Be able to define a two-terminal circuit element.

10.
Be able to define a bilateral device and a linear device, and to determine from an element's v-i relationship if it is bilateral or linear.

11.
Be able to define the v-i relationships (element constraints) for the following two-terminal circuit elements:

$\bullet$ Resistor (Ohm's Law) $\bullet$ Voltage Source
$\bullet$ Current Source $\bullet$ Short Circuit
$\bullet$ Open Circuit $\bullet$ Switch

12.
Be able to state Ohm's Law in terms of resistance R and conductance G.

13.
Be able to use Ohm's Law to find v given i, or i given v, for a resistor with resistance R or conductance G.

14.
Be able to identify nodes and loops in a circuit. In particular, be able to determine the number of nodes and the number of loops in a circuit.

15.
Be able to state Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL).

16.
Be able to assign a ground reference in a circuit, and find voltages relative to the ground reference. (Finding voltages relative to ground reference: delay until Chapter 3.)

17.
Be able to use KVL, KCL and element constraints to write down 2Eequations with 2E unknowns ($v_k, k = 1 \cdots E$ and $i_k, k = 1 \cdots E$) for a circuit with E circuit elements.

18.
Be able to identify parallel and series combinations of circuit elements.

19.
Be able to define ``Equivalent Circuit.''

20.
Be able to find equivalent circuits for the following combinations of circuit elements:

$\bullet$ Resistors in series $\bullet$ Resistors in parallel
$\bullet$ Resistor and voltage source in series $\bullet$ Resistor and voltage source in parallel
$\bullet$ Resistor and current source in series $\bullet$ Resistor and current source in parallel
$\bullet$ Two voltage sources in series $\bullet$ Two current sources in parallel
$\bullet$ Y-connected resistors (not on exam) $\bullet$ $\Delta$-connected resistors (not on exam)

21.
Be able to use voltage division to find voltages across two resistors connected in series.

22.
Be able to use current division to find currents through two resistors connected in parallel.

23.
Be able to find v and i in circuits by circuit reduction: replacing circuit elements with equivalent circuits to reduce the complexity of a circuit.
