PPT-ECE 330: Power Circuits and

Electromechanics Subhonmesh Bose Electrical and Computer Engineering University of Illinois at Urbana Champaign ECE 330 Spring 2018 Course topics Phasors and three phase circuits Magnetic circuits and transformers. Since these circuits remain in standby or sleep mode significantly longer than in active mode their standby current and not their active switching current determines their battery life Hence stringent specifications are being placed on the standby o 1 Motivation Why is power dissipation so important Power dissipation considerations have become important not only from reliability point of view but they have assumed greater importance by the advent of portable battery driven devices like laptops c .

Eng.Mohammed. . Alsumady. Basics of Electronic Components. An electronic component is any device that handles electricity. Electronic components come in many different shapes and sizes, and perform different electrical functions depending upon the purpose for which they are used. Accordingly, electronic equipments make use of a variety of components.. What we’re now learning:. Series Circuit. A . series circuit . has a single path for the current. Series Circuit. There is only one path for the electrons to flow. This means the . current must flow through all loads. Subject Code: 10EC63. Prepared By: Arshiya Sultana, Sreepriya Kurup. Department: ECE.
