What is a Voltage Divider?

A voltage divider is a simple circuit that turns a large voltage into a smaller one using two resistors. It's commonly used to scale down voltage for sensors, analog inputs, and logic levels.

Applications

  • Analog-to-Digital Converters (ADC)
  • Sensor interface
  • Logic level shifting
  • Audio circuits
