By the end of this article, you will have a better understanding of why this book is a valuable resource for your studies.

## Chapter 1: Basic Concepts of Electrical Engineering

The first chapter of the book introduces you to the basic concepts of electrical engineering, such as electric charge, current, voltage, power, resistance, and Ohm's law. You will learn how to apply these concepts to analyze simple circuits using Kirchhoff's laws.

### Subsection 1.1: Electric Charge and Current

In this subsection, you will learn about the nature of electric charge, how it is measured in coulombs (C), and how it can flow through a conductor as electric current (I). You will also learn how to calculate the current in a circuit using the equation I = Q/t, where Q is the charge and t is the time.

### Subsection 1.2: Voltage and Power

In this subsection, you will learn about the concept of voltage (V), which is the difference in electric potential between two points in a circuit. You will also learn how to measure voltage using a voltmeter, and how to calculate the power (P) dissipated or delivered by a circuit element using the equation P = VI, where V is the voltage and I is the current.

### Subsection 1.3: Resistance and Ohm's Law

In this subsection, you will learn about the concept of resistance (R), which is the opposition to the flow of current in a circuit element. You will also learn how to measure resistance using an ohmmeter, and how to calculate the resistance of a wire using the equation R = ρL/A, where ρ is the resistivity, L is the length, and A is the cross-sectional area of the wire. Finally, you will learn about Ohm's law, which states that the voltage across a resistor is proportional to the current through it, or V = IR.

### Subsection 1.4: Kirchhoff's Laws and Circuit Analysis

In this subsection, you will learn about two important laws that govern the behavior of circuits: Kirchhoff's current law (KCL) and Kirchhoff's voltage law (KVL). KCL states that the sum of the currents entering a node (a point where two or more wires meet) is equal to the sum of the currents leaving it. KVL states that the sum of the voltages around a closed loop (a path that starts and ends at the same point) is zero. You will also learn how to use these laws to analyze simple circuits with resistors and voltage sources.

## Chapter 2: AC Circuits

The second chapter of the book introduces you to the concepts of alternating current (AC) circuits, which are circuits that have sources or loads that vary sinusoidally with time. You will learn how to represent AC signals using phasors, how to calculate the impedance and admittance of circuit elements, how to analyze AC power and power factor, and how to design series and parallel resonance circuits.

### Subsection 2.1: Sinusoidal Signals and Phasors

In this subsection, you will learn about sinusoidal signals, which are signals that have the form v(t) = Vm sin(ωt + φ), where Vm is the peak amplitude, ω is the angular frequency, and φ is the phase angle. You will also learn how to represent sinusoidal signals using phasors, which are complex numbers that have the form V = Vmφ, where Vm is the magnitude and φ is the phase angle.

In this subsection, you will learn about impedance (Z) and admittance (Y), which are generalizations of resistance and conductance for AC circuits. You will learn how to calculate the impedance and admittance of resistors, capacitors, and inductors using phasors, and how to use Ohm's law for AC circuits, which states that V = IZ or I = VY.

### Subsection 2.3: AC Power and Power Factor

In this subsection, you will learn about AC power, which is the rate at which energy is transferred in an AC circuit. You will learn how to calculate the instantaneous power (p), the average power (P), and the reactive power (Q) in an AC circuit using phasors.

You will learn how to calculate the power factor using phasors or using the equation PF = cos(θ), where θ is the angle between the voltage and current phasors.

### Subsection 2.4: Series and Parallel Resonance

In this subsection, you will learn about resonance, which is a phenomenon that occurs when an AC circuit has a frequency that matches its natural frequency. You will learn how to design series and parallel resonance circuits using resistors, capacitors, and inductors, and how to calculate their resonant frequency (fr), bandwidth (B), quality factor (Q), and selectivity (S).
