Voltage Divider Circuit Explained

Formula

A voltage divider uses two series resistors to produce a lower output voltage from a higher input. The formula Vout = Vin × R2/(R1+R2) is essential for biasing circuits, sensor interfaces, and level shifting in electronics.

Common use cases:

  • Sensor signal conditioning
  • Microcontroller input voltage scaling
  • Reference voltage generation
