What’s a Voltage Divider?
Think of a voltage divider like splitting a pie into two slices. Instead of pie, you’re splitting voltage. By placing two resistors in a row, you can tap into the middle and get a smaller voltage that’s just the right size for your project.
The math is simple:
Vout = Vin × R2 / (R1 + R2)
Don’t worry if that looks intimidating — it just means the output voltage is a fraction of the input, set by the size of the two resistors.
Voltage dividers are cheap, simple, and great for light-duty jobs like feeding a sensor or microcontroller input. The catch? They’re not good at powering anything that needs steady current. For that, you’ll want a proper voltage regulator or converter.
