The book contains 50 projects in all complete with comprehensive functional description, Parts list, Construction details such as PCB and Components' layouts, Testing guidelines, suitable alternatives in case of uncommon components and lead/pin identification guidelines in case of Semiconductor Devices and Integrated Circuits (ICs). the first three introductory chapters contain a lot of practical information. the first chapter gives operational basics and application relevant information in case of electronic components such as Resistors, Capacitors, Coils, Transformers, Diodes, Transistors, LEDs, Displays, SCRs, Opamps, Timers, Voltage Regulators and General purpose digital ICs such as Gates, Flip flops, Counters etc.Since the emitter potential of transistor (Q1) is less than its base potential by two diode drops, (Q1) is surely in cut-off. As a result, no voltage appears at the collector of (Q1) and hence the drive circuit for the DC/AC inverter portion ... power is ON, the battery is getting charged but is not supplying any power to the DC/AC inverter circuit feeding the fluorescent tube. ... the output of 555 timer is LOW) of the transistor (Q2), energy is stored in the primary of the inverter transformer and duringanbsp;...
