Voltage Divider Calculator

 

Enter input:

          
  Total voltage: VT = Volts [V]  
  Resistance of first load: R1 = Ohms [Ω]  
  Resistance of second load: R2 = Ohms [Ω]  
  Resistance of third load:

(optional)

 R3 = Ohms [Ω]  
         
 

Result:

          
  Voltage drop in R1: V1 = Volts [V]  
  Voltage drop in R2: V2 = Volts [V]  
  Voltage drop in R3: V3 = Volts [V]  
             

In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them.
