How long does it take for the shock to travel the circumference of the stadium? |
|
| |
Well, Wembley Stadium has a circumference of 1km. |
|
| |
Given that C is about 2.9979 x 10^8 m/s in a vacuum, and the current is passing through the heads of football supporters (which approximates fairly closely to vacuum) it would take about 3.3 microseconds for a pulse to make the transit. |

If you wish to be demeaned and humiliated again, let us know, unless it's some sort of sick, perverted and degrading sexual act in which case [xenzag] will oblige, for a fee. |

So with quite a bit of calculation you were able to more
closely approximate the speed eh? Bet you're a smooth one
with the ladies. |
|

Last time I checked (hmm, better check if I ever checked at
all...) electricity doesn't move at the speed of light. What's
the conductivity of a human? |

So... my Mom, my little brother and I went to this Halloween haunted house sponsored by the Edmonton radio station 630 CHED when I was nine and he was seven.
The first people/victims of the tour shut the place down within half an hour of its opening but not before we were out the door and pretty much traumatized for life... I shit you not.
Before you even enter the barn they've staged for the event ghouls climb from graves and drag a shill member of your party back into the ground kicking and screaming as we were shuffled into the dark.
Then came the pitch black back-less staircase climb with people grabbing your ankles from behind them and tickling you from above with what I suppose were feather dusters but felt an awful lot like walking through spider webs and crawling insects.
Then it was on to getting through the strobe-light rubber snake pit room with people above controlling the snakes like marionettes and people thrashing with them on the floor, to be followed by the wailing and moaning car crash victim scene with body parts strewn about and eyeball and such hanging, through to the "surgery" where the 'patients' screamed bloody murder and flailed as the actual animal intestines they'd used were pulled and sliced from what appeared to be their real bodies... |
|
| |
There was a bunch of other scenes and rooms you had to get through too but I don't remember them all anymore and I'm pretty sure I blocked a few. Give me a break. I was nine. |
|
| |
I do remember that the last room had a man sitting in an electric chair and we were all told to line the benches around his court hearing. They read off the list of rapes and murders he'd committed and we were to determine if he went free or got the chair before we could leave. |
|
| |
All the adults cheered for the chair, so they pulled the switch and a current passed through the seats and scracked every one of our asses before they opened the doors and let any of us out. |
|
| |
There were ambulances and cops arriving while we were leaving. |
|
| |
Sadly I don't recall the speed at which the current traveled through he group or even which direction it came from. |
|
| |
No! I flash-backed and the guy on the far right definitely jerked first.
So the charge went counter clockwise around the group and I would place it at less than a sixteenth of a second for the twelve of us. I remember that because they made a big deal about the number of the jury. The group was bigger when they let us in. |

Are you just leaning on the toggle, or is that a character-building
variant of "wax on, wax off"? |
|
| |
No, just his normal schizoid behaviour... |
|
| |
// electricity doesn't move at the speed of light. // |
|
| |
... in solids, no. The crude approximation was merely a bit of gratuitous provocation at the expense of sports fans. |
|
| |
// What's the conductivity of a human? // |
|
| |
As pointed out, highly variable - but conductivity doesn't relate to the propagation of a current. Inductance and capacitance - impedance - does make a difference though, and that's frequency dependant. For a pulse, a single low-to-high transition, you need to include a step function <link>. The rise time of the edge, never a perfect square wave, becomes critical. |

Oh yes, thanks to our famous chat-up line, "Resistance is Futile... " |
|
| |
We always thought it was the chloroform. |

Only if the Rohypnol takes too long to act ... |

My stepdad, older brother, the family cat, and I tried this
with a grill igniter sometime around 1999. It didn't even
reach the next person, let alone the cat at the end of the
circuit. |
|
| |
Should have put the cat first... |
|
| |
It was only the lowered stance of my nine year old self that made the reaction of the much taller people around me appear to travel counter-clockwise. To all other participants besides myself and my younger brother the electrocution effect would have appeared to be clockwise. |
