| 879471 | 2010-04-24 01:21:00 | I had a dream last night where this happened. In my dream none of the lights were working, computer monitors were all showing snow, and when I checked the electricity meter and it said the AC frequency was 236kHz. What would actually happen if this was true? |

Also, I believe all switchmode power supplies would work (such as computer, laptop, etc). This is because they rectify the power as the very first step before chopping it up again. HOWEVER, this is assuming that that high frequency power made it into your house. The transformers in between the power station and your house (ie at substations and your neighborhood) probably wouldn't work on that high frequency power. This is a guess, though, and is not based on solid knowledge :p |

| 879479 | 2010-04-24 02:56:00 | Are you a plane buff Agent? The AC voltages are 400 Hz you might have been having an aviation dream, better than a wet dream. | prefect (6291) | ||
| 879480 | 2010-04-24 03:05:00 | Not really, I didn't even know 400 Hz AC was used in aircraft Looks like today is a good day for learning things! |
