In this module, the operational amplifier, more commonly called the op amp is introduced and used as a circuit element. While the op amp is not a fundamental circuit element, practical op amps display nearly ideal behaviour, thereby allowing one to construct many useful circuits with relative ease. Consequently, there are two motivations for studying the ideal op amp and common op amp circuits; Firstly, op amp circuits provide practical examples to practice the many circuit analysis techniques learned in the other modules. Secondly, op amps provide an easy way to implement many useful circuits. This module aims to cover the op amp at a level compatible with these two goals.

In this module, the concepts of electric charge and interacting forces between charges are discussed.  This module begins with a brief review of vector notations in both 2-dimension and 3-dimension to aid in the study of electric force vectors. Coulomb’s law is the main focus of the discussion on electric force. The force of repulsion as well as attraction between two point charges is studies first, followed by the discussion of the use of superposition principle in the treatment of net force acting on a point charge due to multiple charges.
