Industrial Electronics N4 notes provide essential knowledge for the TVET Report 191 program, focusing on the principles and applications of electronic components in industrial systems. The curriculum was recently revised (effective May 2024), reducing the syllabus from nine to six core modules.
The ratio of the peak value to the RMS value. For a sine wave, this is always 1.414. Components in AC Circuits Pure Resistance (

High voltage gain but low current gain (less than 1). Excellent for high-frequency applications due to low input impedance.
: Atomic theory, PN-junctions, Zener diodes, and rectification.
The Industrial Electronics N4 curriculum covers a wide range of topics, including:
Controls the vertical scale, allowing you to calculate peak voltage (
: Kirchhoff's Laws, Superposition Theorem, Thevenin’s and Norton’s Theorems.
Students frequently lose marks by mixing up current-controlled BJTs with voltage-controlled FETs. Remember that a BJT requires base current ( Ibcap I sub b ) to control collector current ( Iccap I sub c
