The Essentials: Voltage, Current, Resistance

These are the foundations of electronics. Search YouTube/Google if you are unsure of them.

Having a solid understand of electronics basics sets the foundation for what you can learn in terms of PCB design.

I would recommend at least understanding these terms/concepts before continuing:

  • Circuits (open vs closed)
  • Switches (and what they do as an electrical component in general)
  • Voltage (V), Current (I), Resistance (R)
  • Ohm’s Law (V = IR)
  • Resistors
  • AC Power vs DC Power
  • Electric circuit diagrams
