Lesson 1-4 Review …Lesson 5-8 Intro

Lesson 1: Component Parts ID Resistors Capacitors Diodes Transistors Switches Speakers Lamps Transformers Batteries Vacuum tubes Integrated Circuits (IC) Voltage Regulators

Electronic Parts (Collection & Identification) Keep your eyes open Think about organizing yourself Keep leads as long as possible

Lesson 3: Schematic Drawings Pictorial Drawings Components are represented by symbols

Lesson 4: Resistors & Capacitors Resistor colour code Ohms, Watts Value of a capacitor Non-Polarized, Polarized Fixed, Variable Capacitance (Farads), Voltage Rating

Lesson 5: Solid State Components Diodes, SCR’s, Transistors, & LED’s Silicon, germanium Polarity SCR (silicon controlled rectifier) Gate – conducts when triggered by positive voltage Transistor –uses a small amount of voltage or electrical current to control a larger change in voltage or current. –Base, Emitter, Collector –PNP, NPN

Integrated Circuits (IC’s) Basically a pkg of components (programmed) –TTL (Transistor-Transistor Logic) –CMOS (Complimentary – Metal oxide semiconductor) –Plug into sockets soldered into circuit board

Lesson 6: Manufacturing, Selection & Pricing of electronic parts How parts are made Spec sheets price

Lesson 7: Printed Circuit Boards What they are –Wires replaced by conductive strips etched onto board Why –4 main reasons Design techniques –5 rules Design your own printed circuit board

Lesson 8: Electronic Circuits Today What is an electric circuit? –Current, voltage, resistance The Electron, Matter, Elements & Molecules, Atoms Energy Transformation
