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.

https://youtu.be/EQtwsWJuUPs Understanding voltage dividers means understanding Ohm’s Law.  A common use for a voltage divider in most projects is to monitor a battery.  Say you are powering your circuit with a 9V or 12V battery. Microcontroller boards don’t do well with those voltages.   In a future video, we’ll come back and look at more circuits that can use voltage dividers. Episode Notes Correction: There is a mistake around 3:00.  I say “91 millivolts” and I should…
