## Introduction

This resistor calculator calculates the resistance value of different resistors connected in series or in parallel.

Two simple ways to connect circuit elements as below:

### Resistor in Series

The resistors are said to be in series when they are chained together in a single line.

If you can move your finger along the wires from A to B without passing a junction, i.e., without ever having a choice of which wire to follow, the components are connected in series.

### Resistor in parallel

The resistors are said to be in parallel when there terminals are connected to the on two same nodes.

If you ever have a choice of which wire to follow when moving from A to B, the circuit elements are not in series.

If each element provides an alternative path between the same points A and B, the elements are in parallel.

### Parallel Resistor

### Series Resistor

## Calculate the total parallel resistance

Note: You can increase the number of resistors for multiple resistance connected in series or parallel.

## Calculate the total series resistance

Note: You can increase the number of resistors for multiple resistance connected in series or parallel.
