Resistor voltage divider calculator is used to obtain a voltage that is different from available supply. You need such voltage divider for various electronics and electrical projects.


  1. Enter input voltages in V1
  2. Enter values of all resistors where RL is the load resistor.
  3. Vloaded represents the load voltage which is present.
  4. Vout represents output voltage across Rwithout load.


  • You can calculate the input power delivered by the source and the output power delivered to the load.
  • You can find the current using this voltage divider current calculator so as to achieve the current that will go to the load.
  • You can understand the original voltage and impact of load on the voltage.
