Voltage Divider Network

Scale down input voltages for sensitive DAQ/Microcontroller inputs.

Input Voltage (Vin)

Resistor R1 (Ω)

Resistor R2 (Ω)

Output Voltage (Vout)

0.00 V

Vout = Vin * (R2 / (R1 + R2))

Why use a Voltage Divider?

Voltage dividers are indispensable in lab instrumentation to match high-voltage signals to the input range of low-voltage ADCs (e.g., 3.3V or 5V). Always ensure your resistors are rated for the total power dissipation (P = V²/R) to avoid thermal drift or component failure.
