Electronics Engineering

✴The goal of this App is to provide some basic information about electronic circuits. This App supplies basic information on how to use electronic components and explains the logic behind solid state circuit design. Starting with an introduction to semiconductor physics, the chapters moves on to cover topics such as resistors, capacitors, inductors, transformers, diodes, and transistors. Some of the topics and the circuits built with the components discussed in this App.✴►This App should be useful for all readers who want to gain preliminary knowledge regarding the basic components used in electronic circuits.✦ 【Topics Covered in this App are Listed Below】⇢ What is Electronics?⇢ Materials⇢ Quantum Numbers⇢ Pauli Exclusion Principle⇢ Energy Bands⇢ Forbidden gap⇢ Insulators⇢ Semiconductors⇢ Conductors⇢ Energy Bands Important Terms⇢ Ohm’s Law⇢ Semiconductors⇢ Conduction in Semiconductors⇢ Intrinsic Semiconductors⇢ Extrinsic Semiconductor⇢ Hall Effect⇢ Types of Currents⇢ Resistors⇢ Resistors Colour Coding⇢ Resistors Important Terms⇢ Circuit Connections in Resistors⇢ Resistors in Parallel⇢ Non- linear Resistors⇢ Thermistor⇢ Photoresistor⇢ Varistors⇢ Surface Mount⇢ Linear Resistors⇢ Fixed Resistors⇢ Carbon composition⇢ Wire wound⇢ Thick Film⇢ Thin Film⇢ Wattage⇢ Capacitors⇢ Working of a Capacitor⇢ Charging of a Capacitor⇢ Dielectric behaviour of Capacitor⇢ Capacitor Colour Coding⇢ Capacitive Reactance⇢ Temperature Coefficient of Capacitors⇢ Circuit Connections in Capacitors⇢ Capacitors in Parallel⇢ Types of Capacitors⇢ Variable Capacitors⇢ Tuning Capacitors⇢ Trimmer Capacitors⇢ Fixed Capacitors⇢ Ceramic Capacitors⇢ Film Capacitors⇢ Paper Capacitors⇢ Metal Film Capacitors⇢ Other Capacitors⇢ Polarized Capacitors⇢ Electrolytic Capacitors⇢ Aluminium Electrolytic Capacitors⇢ Tantalum Electrolytic capacitors⇢ Niobium Electrolytic Capacitors⇢ Super Capacitors⇢ Double-layered Capacitors⇢ Pseudo Capacitors⇢ Hybrid Capacitors⇢ Inductors⇢ Working of an Inductor⇢ Inductance⇢ Self-Inductance⇢ Mutual Inductance⇢ Factors affecting Inductance⇢ Coefficient of Coupling⇢ Circuit Connections in Inductors⇢ Inductors in Parallel⇢ Inductive Reactance⇢ Types of Inductors⇢ RF Inductors⇢ Chokes⇢ Transformers⇢ Step-up and Step-down Transformers⇢ Types of Transformers⇢ Air-core Transformer⇢ Iron Core Transformers⇢ Auto Transformer⇢ Transformers based on Usage⇢ Measurement Transformers⇢ Distribution Transformers⇢ Transformer Efficiency⇢ Induced EMF in Transformer⇢ Losses in Transformers⇢ Power of a Transformer⇢ Efficiency of a transformer⇢ Diodes⇢ Biasing of a Diode⇢ Working under Forward Biased⇢ Working under Reverse Biased⇢ Purpose of a Diode⇢ Characteristics of a Diode⇢ Junction Diodes⇢ Rectifier Diode⇢ Zener Diode⇢ Switching Diode⇢ Special Purpose Diodes⇢ Tunnel diode⇢ Schottky Diode⇢ Optoelectronic Diodes⇢ Photodiode⇢ Solar Cell⇢ LED (Light Emitting Diodes)⇢ Laser Diode⇢ Principle of Laser Diode⇢ Transistors⇢ Constructional Details of a Transistor⇢ Transistor Biasing⇢ Operation PNP Transistor⇢ Operation NPN Transistor⇢ Transistor Configurations⇢ Common Emitter (CE) Configuration⇢ Common Collector (CC) Configuration⇢ Transistor Regions of Operation⇢ Transistor Load Line Analysis⇢ Types of Transistors⇢ Bipolar Junction Transistor⇢ Field Effect Transistor⇢ Junction Field Effect Transistor⇢ Drain Characteristics of JFET⇢ MOSFET⇢ Construction of a MOSFET⇢ Classification of MOSFETs⇢ Construction of N- Channel MOSFET⇢ Working of N - Channel (depletion mode) MOSFET⇢ Working of N-Channel MOSFET (Enhancement Mode)⇢ P - Channel MOSFET⇢ Drain Characteristics⇢ Comparison between BJT, FET and MOSFET⇢ Nodal Analysis⇢ Mesh Analysis⇢ 14 Thevenin and Norton Equivalent Circuits
