This guide summarizes the core modules of the Industrial Electronics N4 curriculum (revised 2024), focusing on the critical formulas and theoretical concepts you'll need for your notes and exam preparation. 1. Network Theorems
This module focuses on analyzing complex DC circuits where standard series/parallel rules don't easily apply. Kirchhoff's Laws:
Current Law (KCL): Sum of currents entering a junction equals the sum of currents leaving (
Voltage Law (KVL): Total voltage around a closed loop equals zero (
Superposition Theorem: Analyzes circuits with multiple power sources by looking at one source at a time.
Thevenin’s Theorem: Simplifies any complex linear circuit into a single voltage source ( VTHcap V sub cap T cap H end-sub ) and a series resistor ( RTHcap R sub cap T cap H end-sub 2. Alternating Current (AC) Theory Focuses on how components like resistors ( ), inductors ( ), and capacitors ( ) behave under AC signals. Impedance ( ): The total opposition to current in an AC circuit ( Resonance: Occurs when , resulting in minimum impedance in series circuits. Power Factor: The ratio of real power to apparent power ( 3. Semiconductors and Transistors
Covers the physics of electronic components and their use in switching and amplification.
Diodes: PN junction basics, Zener diodes for voltage regulation, and Varactor diodes for tuning.
Transistors (BJT): Focuses on Common Emitter configurations. Gain Calculations: Voltage Gain ( AVcap A sub cap V ):
