BASIC ELECTRICAL ENGINEERING

Brief Overview of Topics discussed in this book:

1. Ohm’s Law: Describes the relationship between voltage, current, and resistance in an electrical circuit: (V = IR).
2. KVL, KCL: Kirchhoff’s Voltage Law and Kirchhoff’s Current Law are fundamental principles used for analyzing electrical circuits.
3. Nodes, Branches & Loops: Fundamental elements in a circuit. Nodes are points where components are connected, branches are paths between nodes, and loops are closed conducting paths.
4. Series elements & Voltage Division: Describes components connected in series and the division of voltage among them.
5. Parallel elements & Current Division: Relates to components connected in parallel and how the current divides among them.
6. Star-Delta transformation: A method to convert a star (or Y) connection into an equivalent delta (or Δ) connection and vice versa.
7. Independent & Dependent Sources: Independent sources have constant voltage or current, while dependent sources depend on another element in the circuit.
8. Source Transformation: A technique used to simplify circuits by transforming voltage sources in series with a resistor into equivalent current sources in parallel with the same resistor and vice versa.
9. Review of Complex Number & Phasor Representation: Complex numbers and phasors are used to analyze AC circuits.
10. Phasor Relationships with Resistance, Inductance, and Capacitance: Define how voltage and current vary in circuits containing resistances, inductances, and capacitances.
11. Series and Parallel Combinations of Inductors and Capacitors: Describes the equivalent inductance and capacitance for inductors and capacitors connected in series and parallel.
12. Mesh and Nodal Analysis: Techniques used to analyze circuit variables like current and voltage.
13. Average, RMS Values & Power Calculations: Concepts used in analyzing the power in AC circuits.
14. R-L, R-C, R-L-C Series Circuits: Circuits containing combinations of resistors, inductors, and capacitors in series.
15. Real, Reactive & Apparent Power & Power Triangle: Concepts defining the different forms of power in AC circuits.
16. Series and Parallel Resonance: Conditions under which circuits containing inductors and capacitors resonate.
17. Thevenin’s, Norton’s, Superposition, Maximum Power Transfer, and Reciprocity Theorems: Various methods and theorems used to analyze and simplify electrical circuits.
18. Single Phase Transformer, Single Phase Induction Motor, and DC Motor: Fundamental electrical machines and their operating principles.
