The aim of this course is to make one competent in analyzing electrical circuits and performing basic electrical measurements to verify circuit concepts experimentally. In this course, students will be introduced to the concepts and definitions of charges, currents, voltages, power, and energy. Apply simplifying techniques to solve DC circuit problems using basic circuit theorems and structured methods like node voltage and mesh current analysis. The goal also includes derivation of the transient responses of RC and RL circuits, steady state response of circuits to sinusoidal excitation in time domain, application of phasors to circuit analysis, introduction to non-linear electronic devices.
