The complex generalisation of Ohm's law, V=IZ, still describes the behaviour of capacitors and inductors. V, I and Z are assumed in this case to be complex variables of the form e^[j(wt + \phi)], modelling each frequency component independently. w = frequency, \phi = phase offset.

At least this got modded down, but it's threads like this where you discover how many ignorant 'nerds' there are on /.

Ohm's law does not only describe resistors. While the schoolboy formulation V=IR (also, admittedly, the law Ohm actually published) describes the instantaneous relationship of voltage and current through a resistor, in modern engineering and physics it is generalised in various ways. For circuit analysis, it becomes V=IZ, where Z is the complex impedance, and describes the time-varying relationship of voltage and current in resistors, capacitors, inductors and pretty much anything else you will find in a circuit. For things other than circuits, the generalisation J=E\sigma describes the relationship between electric field intensity, current density and conductivity.

While certain materials are described as 'non-Ohmic', what this really means is that \sigma is not a constant for those materials and depends on something else, usually the value of E.

Accuracy has never been very important to /., has it?

They were charged with conspiracy to pervert the course of justice by withholding evidence from police. There is no charge that they were involved in voicemail hacking (though of course there are plenty of allegations that they were).

The advantage of these ventures is that they're outside national jurisdiction. The problem with these ventures is that they're outside national jurisdiction - and for almost every company out there, they benefit from the protection of a country's laws more than they suffer from them.

Sealand failed because anyone who hosted data there was wide open to the whim of Roy Bates - and if you didn't like his whim, you had no recourse. This will be no different.
