How to Select a Resistor

When I was working on the next version of Common Parts Library, I realized that it would be helpful to explain why you might pick one type of passive component over another. We started off by writing “How to Select a Capacitor” last month, and are following it up with a close look at resistors this month. In this blog, we will explain all the different types of resistors, their merits and demerits, and popu ...
