The course constitutes an important building block for all electrical engineers and it is the logic continuation of Electric Circuit I. The course starts with the application of the tools gained in Electric Circuits I to investigate the performance of electric circuits comprising operational amplifiers. The course then moves to cover the techniques employed to analyze electric circuit supplied from sinusoidal source(s). These techniques are then applied to calculate the electric power in both single phase and three phase circuits. Finally, Laplace’s Transform is introduced in this course as a general approach to analyze electric circuits in both time domain and frequency domain and applications of this transform are also
