This course enables students to master analysis of physical circuits through the use of Kirchhoff’s laws and ideal circuit element models. Strong emphasis is placed on the formulation of nodal equations for linear resistive circuits as a foundation, but generalizations necessary for handling nonlinear elements are also highlighted. Consequences of linearity are emphasized through superposition and Thevenin/Norton equivalents. Transient analysis of second order circuits with unit step inputs and switched dc sources is emphasized to promote understanding of time-domain linear circuit response. For linear circuits excited with sinusoidal sources, phasor and frequency domain analysis techniques for determining steady state response are emphasized. Application of complex power calculations is also highlighted. The overall course objectives are the following:
