10. Active and Passive An active component is an electronic component which supplies energy to a circuit. Common examples of active components include: Voltage sources Current sources Generators (such as alternators and DC generators) All different types of transistors (such as bipolar junction transistors, MOSFETS, FETs, and JFET) Diodes (such as Zener diodes, photodiodes, Schottky diodes, and LEDs) A passive component is an electronic component which can only receive energy, which it can either dissipate, absorb or store it in an electric field or a magnetic field. Passive elements do not need any form of electrical power to operate. Common examples of passive components include: Resistors Inductors Capacitors Transformers 10/19/2022 10 S.GURUPRASAD SRI VENKATESWARA INSTITUTE OF SCIENCE AND TECHNOLOGY

14. An  electrical source transformation  (or just ”source transformation”) is a method for simplifying circuits by replacing a voltage source with its equivalent current source, or a current source with its equivalent voltage source. Source transformations are implemented using Thevenin’s theorem and Norton’s Theorem. 10/19/2022 14 S.GURUPRASAD SRI VENKATESWARA INSTITUTE OF SCIENCE AND TECHNOLOGY Source Transformation- Voltage - Current
