The Electronic Principles channel explains the theoretical and practical aspects of electronics. The main functions of an inverter are thoroughly explained in this channel by explaining different inverter ics like SG3525A, SG3524, CD4047, TL494 etc. It also explains the functions of different integrated circuits (IC) like NE555, LM324, LM358, TL084 etc. This channel also explains the fundamental electronic laws like ohm's law, KVL, KCL, voltage divider rule, superposition theorem etc.
