Frequently Asked Questions (FAQ)

Q: What is a voltage divider?
A simple passive circuit that turns a large voltage into a smaller voltage using two series resistors.

Q: Why are resistor values in KOhms?
Using kΩ resistors limits current consumption and power dissipation (P = V²/R), which is ideal for signal conditioning.

Q: What is the limitation of this circuit?
Voltage dividers are not suitable for driving high-power loads because the output voltage will drop significantly under load (due to internal resistance).
