Default Re: A lesson about resistance learned the hard way

It wouldn't have been that bad had you un-coiled the cord.

The coil acts like an inductor.

Six computers = high AC currents flowing in that coil = high Inductance. Imagin the magnetic field around that coil!!!

The high current through the coil induces an EMF. This is what generates the heat.
