Electricity lesson

From the Los Angeles Times:

Power transmission: A graphic in Tuesday's Section A about the role of transformers in distributing power to homes referred to current being stepped up to hundreds of thousands of volts on its way from the generating plant to a receiving station.

Believers in Ohm's Law can breathe a sigh of relief. By the way, here's the source the Times misquoted when discussing stepping up voltage for long-distance transmission.
