Start from charge, voltage, current, Ohm and Kirchhoff before moving to network theorems, signals and instruments.
This volume starts at true introductory level. It builds electrical quantities and sign conventions first, then resistive DC networks, Kirchhoff's current law and Kirchhoff's voltage law, nodal and mesh analysis, sources and superposition. Thévenin/Norton only appears after that foundation, followed by measurement, signals, phasors, AC response and oscilloscope practice.
Courses are arranged as a reading sequence. Available material opens normally; planned entries remain visible so the intellectual structure is explicit before the library is complete.
What electrical charge is, how potential difference becomes voltage, what current measures, and how energy and power enter circuit reasoning before any network theorem.
Voltage and current arrows, receiver/generator conventions, sign interpretation and the AoN DC/time/phasor notation system.
Resistance, conductance, linear I–V behaviour, power in a resistor and first one-loop calculations.
Charge conservation at nodes and potential bookkeeping around loops, with explicit sign conventions, worked networks and model limits.
Derive series and parallel equivalents from Kirchhoff's laws and Ohm's law, then build divider formulas and understand loading limits.
Turn Kirchhoff’s laws and Ohm’s law into systematic node-voltage and mesh-current methods, with supernodes/supermeshes when needed.
Independent/dependent sources, source transformations, linearity, superposition and preparation for network equivalence theorems.
Source/load models, terminal behaviour, extraction methods, measurement loading, source-resistance design and power transfer.
DMM operation, source/input resistance, loading, grounding, uncertainty and reproducible DC measurements.
Time-domain quantities, waveforms, amplitude, offset, period, frequency, phase and disciplined notation from constant values to real sinusoidal signals.
Complex amplitudes derived from real sinusoids, then impedance, admittance, phase relations and systematic sinusoidal-network solution.
Complex input/output response versus frequency, then magnitude/phase, poles/zeros, Bode representation and bandwidth.
Electrical input/reference model, probes and loading, triggering/time base, source impedance, bandwidth/rise time and reproducible measurements.
