Resistor Calculator

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.
