A common question that comes up about pull-up resistors: what value do you pick and why not just use a piece of wire? In this follow-up electronics tutorial, the bald engineer looks at how to pick pull-up resistor values.

Previously, we looked at resistor voltage dividers. Sometimes I get questions about using these instead of regulators. In this video, I show why that doesn’t work. In fact, I go one step further and show that Zener regulators do not work either.
