Content	Chapter 1. Mathematical reminders about complex numbers (NC) Cartesian form, conjugated NCs, Module, Arithmetic operations on NCs (addition, etc.), Geometric representation, Trigonometric form, Moivre formula, root of NCs, Representation by an exponential of an NC, Trigonometric application of Euler\'s formulas, Application to NC electricity. Chapter 2. Reminders on the fundamental laws of electricity Continuous regime: electric dipole, association of dipoles R, C, L. Harmonic regime: representation of sinusoidal quantities, average and effective values, Fresnel representation, complex notation, impedances, powers in sinusoidal regime (instantaneous, active, apparent, reactive), Boucherot\'s theorem. Transient regime: RL circuit, RC circuit, RLC circuit, charging and discharging of a capacitor. Chapter 3. Electrical circuits and powers Single-phase circuits and electrical powers. Three-phase systems: Balanced and unbalanced (symmetrical components) and electrical powers. Chapter 4. Magnetic circuits Magnetic circuits in sinusoidal alternating regime. Self and mutual inductances. Magnetic electrical analogy. Chapter 5. Transformers Ideal single-phase transformer. Real single-phase transformer. Other transformers (insulation, impulse, autotransformer, three-phase transformers). Chapter 6. Introduction to electrical machines General information on electrical machines. Principle of operation of the generator and the engine. Power balance and efficiency.
