Resistance network calculator

Resistance Network Calculator

Introduction

Calculate the resistance of any resistor network.

The network is stated with a string. The resistors are separated by a vertical dash. Each resistor has a starting node, an ending node and a resistance, separated by space characters.

Regular 3x3 mesh, using twelve one ohm resistors

0 1 2 3 4 5 6 7 8 Battery connection nodes: 0 and 8 assert 3/2 == network(9,0,8,"0 1 1|1 2 1|3 4 1|4 5 1|6 7 1|7 8 1|0 3 1|3 6 1|1 4 1|4 7 1|2 5 1|5 8 1")

Regular 4x4 mesh, using 24 one ohm resistors

This network is not possible to solve using the Resistor Calculator previous published on Rosetta Code. There is no natural starting point.
