This text is an introduction to the basic principles of electrical engineering and covers DC and AC circuit analysis and Transients. It is intended for all engineering majors and presumes knowledge of first year differential and integral calculus and physics. The last two chapters include step-by-step procedures for the solutions of simple differential equations used in the derivation of the natural and forces responses. Appendices A, B, and C are introductions to MATLAB®, Simulink®, and SimPowerSystems® respectively. Appendix D is a review of Complex Numbers, and Appendix E is an introduction to matrices and determinants.
