Overall Educational Objective

To develop skills in determining DC and AC steady state solutions to electrical networks, and power computations.

Course Learning Outcomes
A student who successfully fulfills the course requirements will have demonstrated:

1. an ability to define and explain the meaning/function of charge, current, voltage, power, energy, R, L, C, the op amp, and the fundamental principles of Ohm's law, KVL and KCL including an understanding of electrical safety and the effect of current on humans.
2. an ability to write the equilibrium equations for a given network and solve them analytically, and also using appropriate software as needed for the steady state (DC and AC/phasor) solution.
3. an ability to state and apply the principles of superposition, linearity, source transformations, and Thevenin/Norton equivalent circuits to simplify the analysis of circuits and/or the computation of responses.
4. an ability to analyze resistive op amp circuits and design inverting, non-inverting, summing, and differential amplifier circuits using op amps.
5. an in depth understanding of the behavior of inductances and capacitances, and differentiating and integrating op amp circuits.
6. an ability to qualitatively and quantitatively predict and compute the steady state AC responses of basic circuits using the phasor method.
7. an ability to compute effective and average values of periodic signals and compute the instantaneous and average powers delivered to a circuit element.
8. an ability to compute the complex power associated with a circuit element and design a circuit to improve the power factor in an AC circuit.
9. an ability to determine the conditions for maximum power transfer to any circuit element.
