What a revolting story - Page 2

SteamWake · 10-25-10, 10:47 AM

I am currently designing the remodel of some "affordible apartments". There two story buildings with about 50 units in each building.

We informed the owner (the city) that new feeders would have to be pulled to new panels in each unit.

We were told not to worry about that as all of the copper had been pulled out long ago

and not by the city.

The main feeders were still there (1,000 amps worth) only because they were aluminum.

The storys I could tell about this little project could make your head spin but I'm not really at liberty to divulge.

Need to up the voltage..... that will stop them!

Well they obviously knew enough to pull the meters before pulling the conductors so 'upping the voltage' wouldent accomplish much.

But I have heard storys about some of these bozos getting into a transmission yard and supprise supprise thats 12,470 volts *POOF*

I once received a shock in excess of 30,000 volts and survived with minor shock and no injury at all. I hooked up a timing light to my car incorrectly. Lots of voltage, current nil. My arm snapped back of it's own accord, hard enough to throw the light about twenty feet.

My arm was sore for a couple of minutes. Lucky me.

Current nil.... thats what saved your life my friend. That and it was DC.

If there had been any available current to speak of you would be a lump of coal right now.

Here is what you can get with a little potential behind it.

Keep in mind that is more or less perfectly normal

Yep, I've seen that one before. On the other hand I've read that out of four 9-volt batteries a stun gun can generate 750,000 volts. No amperage to speak of, so the victim is merely stunned.

We use electricity every day and never think about this stuff. Likewise natural gas. In one of his books John Stossel related that he was told by someone in that field "What if I proposed a new form of energy? One that was a deadly undetectable poison, and highly explosive as well? Now, what If I told you I want to pump this stuff directly into your home? The next time you turn on your stove, or take a hot shower, think about that."

It's sad to admit but I think about electricity nearly 24/7.

Its what I do for a living and in my liesure time I restore old ham radios.

Some of those radios can bite you pretty hard if you arent careful. Fun is brushing against B+ (300 volts DC) or worse.

But 'power' is simply expressed as P=E*I where power is expressed in 'watts or Voltampers' E=Voltage and I=Current.

As you can see if there is a miniscule amount of current there is not really much power.

E? Never seen the letter E, at least not when meaning voltage. I know that formula as P=VI. And most of our books are American so that can't be the problem

SteamWake · 10-26-10, 12:11 PM

Ohm's Law

I = E / R

Its been E as long as I can remeber. E is for electromotive force.

But I see evidently its been changed to V to make it 'easy' I guess since no one really understands EMF anymore.

yep I know Ohms law as V=IR.
Wikipedia has it with V as well, and V is the SI-symbol for Voltage.

It's been V for as long as *I* can remember, but that's just little over 1 year at university and 3 or 4 years at high school.

tater · 10-26-10, 01:15 PM

It was V=IR as an astrophysics major back in the 80s, too, least for circuits.

For fields, we'd use E, though.

Penguin · 10-26-10, 03:37 PM

To complete the confusion: In Germany we use an U instead of a V, maybe to avoid confusion with voltage.
So my bid would be U=I*R

Platapus · 10-26-10, 05:23 PM

I once made an 8 inch screwdriver into a 2 inch screwdriver in about a millisecond because I made the fundamental mistake you can make with electricity.

I asked someone to kill the circuit.

Very bad mistake and I am lucky to be alive.

In high school we did so as well. But on the uni we only use V.
