Calculate the output voltage of a resistive divider circuit. Useful for scaling down voltages for sensor inputs and establishing reference levels in analog circuits.
Yes! If you connect a load with low resistance to Vout, it acts as a parallel resistor to R2, dropping the voltage. Voltage dividers are best for high-impedance inputs.
No. Voltage dividers are inefficient and the voltage will drop drastically under load. Use a voltage regulator for power applications.
Vout = Vin * R2/(R1+R2)
