Optimum Resistors Find Tools

This page is a web application that design circuits of resistors. Use this utility to find the optimum set of resistors for a circuit of resistors from the resistor sequence.


Voltage Divider
V1 (Input Voltage):V
V2 (Desired Output Voltage):V
Select Resistor Sequence:


Voltage Divider2
V1 (Input Voltage) :V
V2 (Desired Output Voltage):V
V3 (Desired Output Voltage):V
Select Resistor Sequence:


Parallel and Series of two Resistors
Equivalent Resistor Ra Parallel Series
Select Resistor Sequence:
Ra (Desired Resistance):
        Ω (10-1000MΩ)

The Ra is resistance to place in parallel and in series of two resistors to create a non standard resistance. This tool find the optimum set of resistors R1,R2 and R3,R4 for a desired Ra value.


Calcurate for resistances to divide a voltage (to branch a current)
Equivalent Resistor Ra Parallel Series
Select Resistor Sequence:
N (The total number of resistors): (2-99)
Ra (Desired Resistance):
        Ω(10-1000MΩ)

Three More resistors circuit is often combined to divide a voltage (to branch a current). This tool find the optimum set of R1,R2…RN resistors for a desired Ra value from a close resistor value as even as combining resistances.
