Electrical Fundamentals

For engineers and technicians building the circuit vocabulary and analysis skills required across all controls, panel design, and machine work. Includes circuit theory, passive components, conductor sizing, and IEC earthing systems.

Recommended entry modules

• Electrical Quantities and Circuit Language — vocabulary and circuit topology
• Kirchhoff’s Laws and Systematic Analysis — systematic analysis for real circuits
• Conductor Ampacity and Termination Temperature — NEC table reading and sizing rules

Module	Level	Time	Type
Electrical Quantities and Circuit Language Core Build the shared vocabulary — voltage, current, resistance, power — and learn to read circuit topology before solving anything.	Beginner	20 min	Concept
Series, Parallel, and Divider Methods Reduce series and parallel networks and apply voltage and current dividers to find operating points in real circuits.	Beginner	25 min	Concept + Practice
Kirchhoff's Laws and Systematic Analysis Core Apply KCL and KVL with nodal and loop analysis to solve circuits that cannot be simplified by series/parallel rules alone.	Beginner	30 min	Concept + Practice
Equivalent Circuit Methods Simplify complex networks to Thevenin or Norton equivalents; apply source transformation and superposition for multi-source problems.	Intermediate	30 min	Concept + Practice
Electrical Equations Reference Quick-reference sheet for Ohm's law, power, dividers, KCL/KVL, and capacitor/inductor energy — formatted for fast lookup.	Beginner	10 min	Reference
Passive Components Understand resistors, capacitors, and inductors — their ratings, stored energy, and behavior in DC and AC circuits.	Beginner	20 min	Concept
Diodes, Transistors, and Switching Basics Cover diode families, BJT/MOSFET/IGBT switching modes, and flyback diodes — the semiconductor layer under every drive and power supply.	Intermediate	25 min	Concept
Conductor Ampacity and Termination Temperature Core Read NEC ampacity tables correctly, apply correction factors, and understand the 60/75°C termination temperature rule.	Beginner	20 min	Code Application
IEC Earthing System Types Understand how TN-C, TT, TN-C-S, TN-S, and IT earthing systems affect fault-current path, protective-device selection, and touch-voltage risk in machine and panel design.	Beginner	20 min	Concept
