Electric Circuits Laboratory Manual

Description

This book provides insights into practical aspects of electric circuits. The author provides real-world examples throughout this book. The devices chosen for this book can be found in nearly all laboratories. No expensive measurement devices are used throughout the book. Someone who reads this book has a better understanding of practical aspects of electric circuits. Chapter 1 introduces tools that will be used in the next chapters. Chapter 2 studies the resistors and contains 9 experiments. Chapter 3 studies the digital multimeters and contains 7 experiments. Chapter 4 studies Kirchhoff's voltage/current law, nodal/mesh analysis and Thevenin equivalent circuits. This chapter contains 5 experiments. Chapter 5 studies the first and second order circuits (RC, RL and RLC) and contains 4 experiments. Chapter 6 studies the DC and AC steady state behavior of electric circuits and frequency response of filters and has 5 experiments. Chapter 7 studies magnetic coupling and transformers and contains 3 experiments. Appendix A shows how different types of graphs can be drawn with MATLAB. Appendix B reviews the concept of root mean square.  978-3-031-24552-7 1 Preface Contents 978-3-031-24552-7_1 1 Commonly Used Labaratory Equipmentes 1.1 Introduction 1.2 Digital Multi Meter (DMM) 1.3 Function Generator (Signal Generator) 1.4 Oscilloscope 1.5 Power Supply 1.6 Breadboard Reference for Further Study 978-3-031-24552-7_2 2 Resistors 2.1 Introduction 2.2 Tolerance of Resistors 2.2.1 Introduction 2.2.2 Procedure 2.3 Measurement of Low Resistances 2.3.1 Introduction 2.3.2 Procedure 2.4 Measurement of Very Low Resistances 2.4.1 Introduction 2.4.2 Procedure 2.5 Series and Parallel Connection of Resistors 2.5.1 Introduction 2.5.2 Procedure 2.6 Ohm’s Law 2.6.1 Introduction 2.6.2 Procedure 2.7 Potentiometer 2.7.1 Introduction 2.7.2 Procedure 2.8 Light Dependent Resistor (LDR) 2.8.1 Introduction 2.8.2 Procedure 2.9 Thermistor 2.9.1 Introduction 2.9.2 Procedure 2.10 Observing the Current Waveform 2.10.1 Introduction 2.10.2 Procedure Reference for Further Study 978-3-031-24552-7_3 3 Digital Multi Meter 3.1 Introduction 3.2 Internal Resistance of DMM in Voltage Measurement Mode 3.2.1 Introduction 3.2.2 Procedure 3.3 Internal Resistance of DMM in Current Measurement Mode 3.3.1 Introduction 3.3.2 Procedure 3.4 Test Current of DMM in Resistance Measurement Mode 3.4.1 Introduction 3.4.2 Procedure 3.5 DC Component (Average Value) Measurement with DMM 3.5.1 Introduction 3.5.2 Procedure 3.6 RMS Measurement with DMM 3.6.1 Introduction 3.6.2 Procedure 3.7 True RMS DMM’s 3.7.1 Introduction 3.7.2 Procedure 3.8 Frequency Response of the AC Voltmeter and AC Ammeter 3.8.1 Introduction 3.8.2 Procedure Reference for Further Study 978-3-031-24552-7_4 4 Circuit Theorems 4.1 Introduction 4.2 Voltage Division, Current Division and KCL 4.2.1 Introduction 4.2.2 Procedure 4.3 Nodal Analysis 4.3.1 Introduction 4.3.2 Procedure 4.4 Mesh Analysis 4.4.1 Introduction 4.4.2 Procedure 4.5 Thevenin Theorem 4.5.1 Introduction 4.5.2 Procedure 4.6 Maximum Power Transfer 4.6.1 Introduction 4.6.2 Procedure References for Further Study 978-3-031-24552-7_5 5 First Order and Second Order Circuits 5.1 Introduction 5.2 Output Resistance of Function Generator 5.2.1 Introduction 5.2.2 Procedure 5.3 Step Response of RC Circuit 5.3.1 Introduction 5.3.2 Procedure 5.4 Step Response of RL Circuit 5.4.1 Introduction 5.4.2 Procedure 5.5 Step Response of Series RLC Circuit 5.5.1 Introduction 5.5.2 Procedure 5.6 Step Response of Parallel RLC Circuit 5.6.1 Introduction 5.6.2 Procedure References for Further Study 978-3-031-24552-7_6 6 Steady State DC and AC Analysis and Filters 6.1 Introduction 6.2 Steady State DC Analysis 6.2.1 Introduction 6.2.2 Procedure 6.3 Steady State AC (Sinusoidal) Analysis 6.3.1 Introduction 6.3.2 Procedure 6.4 Series and Parallel Resonance 6.4.1 Introduction 6.4.2 Procedure 6.5 Low-Pass Filter 6.5.1 Introduction 6.5.2 Procedure 6.6 High-Pass Filter 6.6.1 Introduction 6.6.2 Procedure References for Further Study 978-3-031-24552-7_7 7 Magnetic Coupling and Transformers 7.1 Introduction 7.2 Dot Convention in Transformers 7.2.1 Introduction 7.2.2 Procedure 7.3 Turn Ratio of Transformer 7.3.1 Introduction 7.3.2 Procedure 7.4 Coupling Coefficient of Mutually Coupled Inductors 7.4.1 Introduction 7.4.2 Procedure References for Further Study 1 (1) Appendix A: Drawing Graphs with MATLAB® A.1 Introduction A.2 fplot Command A.3 Plotting the Graph of a Numeric Data A.4 Addition of Labels and Title to the Drawn Graph A.5 Exporting the Drawn Graph as a Graphical File A.6 Drawing Two or More Graphs on the Same Axis A.7 Logarithmic Axis Reference for Further Study Appendix B: Root Mean Square B.1 Introduction B.2 Root Mean Square (RMS) of a signal B.2.1 Example 1 B.2.2 Example 2 B.3 Effective Value of Sum of Two Periodic Signals B.3.1 Example 3 B.3.2 Example 4 B.4 Measurement of RMS of Signals Reference for Further Study
