FAQ
What can Voltage Divider Calculator calculate?
Voltage Divider Calculator can solve for any of the four main values in a voltage divider circuit: Input Voltage (Vin), Output Voltage (Vout), Resistor 1 (R1), or Resistor 2 (R2). It can also calculate the output voltage under load with an optional Load Resistance (RL).
Does Voltage Divider Calculator support loaded dividers?
Yes, the latest version of Voltage Divider Calculator supports loaded divider calculations. You can add an optional Load Resistance (RL) to see the real output voltage under load.
Can Voltage Divider Calculator help with resistor selection?
Yes, Voltage Divider Calculator can help you pick the right resistor wattage by showing the power dissipation for R1 and R2. It also provides the nearest standard E24 resistor value for your calculated resistance.
What units does Voltage Divider Calculator support?
