Electricity |
Electricity is a subject not a substance!Geology, Astronomy and Semantics are subjects - so is Electricity. Electricity does not heat a light bulb filament - electric current heats a filament. There are many, otherwise good authors, who make this mistake. Be warned - the fallacy has many forms and is riddled through most elementary texts in both Chemistry and Physics. The topic would make a good polemic for an extended essay. |
