Dave,

Check out http://www.nationalgeographic.com/lightning/2.html
There are a few errors, but the essence is there. You'll have current in
the hundreds of thousands of Amperes. Nothing is sacred. Anything can be
fried (or spared). My neighbor's house was hit probably 10 or 15 years ago;
she showed me the light bulb that the bolt left/entered into. There is a
nice hole (no sharp edges, very round and smooth edges) in the bulb. It
burned out motors in her house. Quite a mess. She felt her hair stand on
edge when she was lying down on her couch and the bolt struck. Not
pleasant.

Will it blow your modem, even if the phone line is NOT connected to it?

Will it make your answering machine act like it is on drugs?

Will it short out a caller ID box?

Will it cause an OPEN in in 1 line of a 4 conductor phone wire?

Will it losen the ground clamp from the phone wire gnd to the electrical
wire GND ?

Any thoughts from those who know?
Dave!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

well jim .........which way is it........up going down or down going
up.??? i had a friend of mine that came home from work one day
........and found a gaping hole in his roof right over the couch where
he watches tv when he is home......needless to say, being the nice guy
that i am ......i told him.......too bad, if it had been just a little
past 6 in the afternoon, it would have been much better......of course
alas he did not see the humor in that........however , it came down
the big pine tree in his yard and jumped over on his house and blew a
hole in the roof......how about them apples???

I believe I've read that "streamers" go up and there are a number of quick
strikes before the big show. Best bet is do a google search on lightning
and see what turns up. I haven't ever worked with the stuff (thank
heavens!) Of course, if anyone is in the way of it - does it matter if
it goes up or down? BTW there was an article in the newspaper in the last
week or so - some guy finally came home from extensive rehabilitation. He
still is far from normal. He was a boy scout and a tree was hit near where
he was standing. This occurred in the late 1990s and he just came home
within the last two weeks!

How a plasma wire is constructed and how lightning currents
flow are two completely different events - happen at different
times during a CG lightning event. How a streamer is built
has nothing to do with the OPs original question. Lightning,
as his question asks, is not going one direction. Lightning
is a powerful RF wave. IOW it goes both directions. BTW
powerful but typically not that much energy at a strike
location.

What illegal towers? I hope you don't think amateurs are limited to 60 feet
or something. There are no 2 meter CB amps. My guess is that most amateurs
run 100 to 150 watts on HF and anywhere from 5 watts to perhaps 70 watts on
2 meters. That is *plenty* for worldwide communications on HF and
sufficient for a couple of hundred miles of continuous 24/7 coverage on 2
meters (depending upon mode/antenna etc.)

Turns out that the bottom of the cloud is negatively charged and usually is
the cause of cloud to earth strikes. The top of the cloud is positively
charged and can strike 5 or 10 miles out away from the cloud. This means
you can be struck even if you're 10 miles away from the cloud and think
you're safe. Up or down? If you talk electron flow, it can be either way.
The following I clipped from a website:

The average lightning stroke has a peak electrical current of 30,000 amps.
Extreme lightning discharges can reach 10 times that, while some discharges,
especially those within a cloud, are only a few thousand amps. In terms more
people are familiar with, the electricity flowing within a lightning bolt
can reach 200 million volts. Combined with the high amperage, lightning has
enough energy to kill instantly.

So, 200 million volts at 30,000 (possibly 300,000) Amperes. So much for the
shoot-outs LOL.

well dave you have to ask yourself ........how many amperes of pure
current are in a lighning bolt..........


the answer to your question is: all depends.....how close the
'lightning strike' was to your residence........but it can do all the
things you have stated and much more......ask the hambos what happens
when their illegal towers get hit by lightning........


if the flow of electrons goes from negative to positive in the real
world........does lightning go from the ground up or the clouds to the
ground..????? that is the learning question for the pile
today.........



According to weather service, though the lightning is called "Cloud to
Ground" - it is from the ground UP.... As to what all would happen in a
strike, it depends.
Our home was directly hit once, the lightning went up under an awning, blew
out a porch light and went in that way. The CB and every thing else was ok..
The brand new TV set got smoked. So, go figure. I've never - even in my
repair business history - have ever heard of "everything" getting zapped. As
to HOW the items work or not after, depends on how it was affected, though
usually, they won't work at all, if in through a "power" supply. While some
folks feel a set struck by lightning is usually non repairable, that is not
always true. I've seen, heard AND repaired sets or devices that were hit by
lighting with great success.
So, a lighting hit is not always a killer for electronics. I've seen as much
if not more damage done by power surges from Electrical Lines as I have with
lightning.
So, YOU decide which is more damaging..... Actually, I"d bet Electrical
surges are a better bet for probability, as you're always connected.
However, due to our experience from the lightning strike of days gone by,
when a storm is approaching, EVERYTHING in my home except the light bulbs,
furnace, refrigerator is unplugged. The phone is left plugged in to the
phone jack, but modems are unplugged from the computers. The only other
lightning strike I sustained which was not a direct hit, was a preamp on a
2meter repeater receiver got burned out. The receiver was ok. The
transmitter and all else checked out ok. Though my answers are not definite
by any means, these are just my experiences and knowledge of the subject.
