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. 73 from Rochester, NY Jim "Dave or Debby" wrote in message ... 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?

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!) ![]() 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! 73 from Rochester, NY Jim " --- Outgoing mail is certified Virus Free.

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.) 73 from Rochester, NY Jim " --- Outgoing mail is certified Virus Free.

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. 73 from Rochester, NY Jim --- Outgoing mail is certified Virus Free.

Dave!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- 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. C.L. |
