    high voltage resister devider

    :)this looks like it would qualify as the worlds biggest wire wound resister, but this is a high voltage resiter devider, the pvc pipe base used to spiral wound the resister chain of 100x 10m 1/4 watt resisters to give a total resistance of 1000m, this stack will pull 50,000 volts dc first the...
