MBY article on Generators

Has anyone else noticed the rather enormous errors in the table of power ratings of typical appliances, and their equivalent current consumption?

I haven't got the mag in front of me but I was reading it last night and was rather perplexed to read a fridge or something with power of 5W took 5A, yet a hairdryer of 1500W took only 6A !!!

Amazing. I couldn't see any sense to the numbers in that table at all - there was no correlation between power and current whatsoever, despite the guidance at the bottom of the same page clearly explaining how VxA=W !!

...Unless it's me?

Well the hairdryer is correct. But a 5kW fridge? Jesus how big is it?

5kw fridge, just think of how many beers you can get in it!

1500W hairdryer at 230V ~6A

Can't make sense of the fridge. Perhaps 55W? So 55W at 12V ~5A?

Yup, I thought they meant 55w for the fridge, but actually several of the items at the bottom of the table didn't make sense either, it wasn't just the fridge. The writer also committed the cardinal sin in the main text of mixing up current and potential, when he said high voltage meant a lot of electricity running through the wires. But generally a good article imho.

Anyone get the James Bear humour?
