What is a Voltage Divider?

A voltage divider is a simple circuit used to reduce voltage using two resistors connected in series. It’s widely used in analog electronics to create reference voltages or to scale down sensor signals before feeding them into ADCs (Analog-to-Digital Converters).

The output voltage

VoutV_{\text{out}}

is given by:

 

Vout=Vin×R2R1+R2V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2}

Where:

  • VinV_{in}

    is the input voltage

  • R1R_1

    and

    R2R_2

    are the two resistors

  • VoutV_{out}

    is the output voltage taken across

    R2R_2
