Take a Stance, The Resist Stance

Resistors - the most ubiquitous of electronic components. They are a critical piece in just about every circuit. And they play a major role in our favorite equation, Ohm's Law.

In this, our pièce de résistance, we'll cover:

  • What is a resistor?!
  • Resistor units
  • Resistor circuit symbol(s)
  • Resistors in series and parallel
  • Different variations of resistors
  • Color coding decoding
  • Surface mount resistor decoding
  • Example resistor applications
