Electrical Basics
Move beyond low-voltage electronics into household and mains electrical concepts — AC vs. DC, circuit wiring, earthing, and the protection devices (fuses, MCBs, RCCBs) that keep a circuit safe.
10 articles
AC vs DC
Learn how alternating current and direct current differ, how to read AC waveforms, and how rectifiers, inverters, meters, and power supplies are used safely.
Series Circuit
Learn how series circuits share current, divide voltage, combine resistance, dissipate power, and how to measure and troubleshoot a series path.
Parallel Circuit
Understand parallel circuit voltage, current division, equivalent resistance, load budgeting, LED branches, and practical troubleshooting.
Fuse
Learn how fuses interrupt overcurrent, understand current and voltage ratings, choose the correct fuse, test safely, and diagnose repeated fuse failures.
Power Factor
Understand real, reactive, and apparent power; lagging and leading power factor; measurement; and safe correction principles.
Single Phase
Learn single-phase AC fundamentals including RMS voltage, frequency, phase, power calculations, conductors, voltage drop, and protective devices.
Three Phase
Understand three-phase AC, star and delta connections, line and phase voltage, balanced power calculations, motors, and electrical safety.
Earthing
Understand protective earthing, circuit ground, neutral, bonding, fault protection, and safe low-voltage electronics practices.
MCB
Understand MCB operation, overload and short-circuit protection, current ratings, trip curves, breaking capacity, and safe troubleshooting boundaries.
RCCB
Understand how RCCBs detect residual current, their ratings and types, testing limits, nuisance trips, and how they differ from MCBs and RCBOs.
