# 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

## Voltage Divider2

## Parallel and Series of two Resistors

Equivalent Resistor Ra | Parallel | Series | |

→ |

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 | |

→ |

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.
