Resistors — they’re one of the most basic, ubiquitous, easiest to understand electronic component.
Or are they?
Resistors are a critical part of just about every type of circuit, even integrated circuits. They’re also one of the main characters in Ohm’s Law.
We often take them for granted, but there are many types of resistors and choosing the right one for your purpose can make the difference between a widget that works, or a widget that doesn’t work or only works sometimes.
Complete books have been written on resistors, but today I’m just going to talk about the more common resistor types that you’re likely to run into and a little on how/when to use them in your circuits.
