Would electronic equipment that is turned off be fried by an EMP pulse?

EMP can also travel along anything that conducts electricity, not just through the air. Examples of this include phone lines, power lines and network lines . With that being said, any electrical device that is turned off but plugged in, can be "fried".\n\nEven devices not plugged in can also be fried, depending on the intensity of the EMP pulse.\n\nSince there are also wires and many electrical and computerized components in modern cars, the same can also be said for modern cars that are turned off. The same can not be said for older, carborated cars with fewer electrical and little to no computerized components.\n\nUltimately, it really depends on how powerful the EMP pulse is.\n\nI also watch Jericho and had the same questions you did, so I looked up the answers on the internet and posted my source with my answer.

it may just not "turn off"

There are four ways a person can get injured from lightning: a direct strike, "splashes" (when the lightning bounces off something and strikes you), ground strikes (when lightning strikes the ground and then you conduct the electricity), and EMP waves (i don't know what this is). You have a 1 in 3000 chance of being hurt by lightning, and a surge protector lowers that odds even more. So according to the fact that chances are pretty low, I'd say it's safe to stay on the computer.

See this wikipedia entry.\n\nOne type of EMP is a gigantic electromagnetic pulse which is generated when an atomic bomb goes off a few miles above a city. It could induce electrical currents inside electronic equipment for 30 miles around, completely destroying them. It could wipe out all the high technology in a city, leaving people to live in the dark ages.

Likely hood is that you'll do a fair bit of damage.\n\nA) You'll crash your computer. There is now no data to access from Windows.\nB) You will most likely hurt your harddrive. you could short circuit it, wipe data, or break mechanisms within the actual drive.\n\nand most importantly.. You'll most likely hurt yourself. it will cost you money to get this fixed, and you could ELECTROCUTE yourself!\n\nby the way,\nWHY ON EARTH ARE YOU DOING THIS?!?\nYou could stop all of these issues by just turning your computer OFF!\n\n\nPlease don't do this... \nHope this helps,\nmitch

e-mail me: intel_knight-at-yahoo-dot-com\n\nAnd I have no clue how to build that EMP thing, or if it is even possible. I just thought it would be a cool thing to have.

You might start by contacting the power company.  If you have concerns about eletromagnetic interference, they should be willing to help you.

get an uninterruptible power supply...

Yes. Just be sure to test it thoroughly so it doesn't interfere with the other equipment. Crashing a Plane with the internet would be bad for business. Good luck!

Putting it bluntly, No.  To create a discharge like that even for a few seconds you'd prob need a battery pack the size of a pickup and it would still be single use.  I'm pretty sure your local law enforcement would frown upon such devices too.......

Oh boy.  There's no doubting it when it happens.  Depending on the size they will catch fire and you'll smell a combination of copper and ozone.  It will give out a typical pulse signal however some of the pulses may be missing or it won't produce power at all.

If you have a good surge protector, that is one that not only protects the power, but also your modem line or cable, and you have backups, you are reasonably safe.  If not, it would be best to unplug your computer from modem and power.\n\nTo those who say that it is absolutely unsafe to be online during a thunderstorm, do you all think that every business with computers shuts down during thunderstorms?  Of course not.  They just take precautions.  If the home user does not have adequate electrical protection, then she would be wise to disconnect her computer.  If she has adequate protection, then surf away and have fun!

If you have the computer connected to the UPS with the com port cable, and are running XP, you can configure it in the Control Panel.  If you are not connected this way, then when it beeps it is not providing enough power to maintain the equipment plugged into it.  If the cable is in use, and you still can not keep it going during a momentary outage, then you may need to do a firmware upgrade which you can get from the manufacturers site.  Worse case scenario, the battery may need to be replaced. Hope this helps.

I'd like to know exactly what you're trying to do. Using the wrong type of capacitor or one with the wrong values could explode and burn. I'm talking about a pretty violent explosion at 110 VAC!  A Snubber will not work because that is now what they are for. A snubber is used on the gate of SCRs to prevent false retriggering especially on high power circuits. What you need is a Thermistor. This is a flat round device with two wires coming out of the edge. The thermistor will be put in series between the power switch and the capacitor. At normal room temperatures the thermistor might have about 50 Ohms of resistance. When it warms up, (almost instantly), the resistance drops to about zero. This action limits and controls the initial power surge into the capacitor when the switch is thrown thereby preventing damage to the switch. You need to know the voltage and current load to select the right thermistor otherwise it becomes smoke.\n\nPlese use caution: Capacitors can store huge amounts of power and will COMPLETELY DISCHARGE IMMEDIATELY.\n\nA large capacitor, when shorted out, can blow a 1/4 inch screwdriver in half! Sounds cool but the missing part is burning molten metal flying at you! Please be Careful!

Unless you have a surge protector and a backup system, it isn't recommended to leave your computer on. If lightning strikes, it can fry out the electronics in your computer.

I really dont think so, i mean if you are talking about em waves given off by electrical equipment of this kind then no.  The only concern with such equipment is that all the connections are properly in place and there is no lose wiring sticking out of it so that it is earthed properly and completely safe.

You don't "use" it, it's passive. If your computer is plugged into a power strip with a surge protector or has one of its own on its power cable, it's already active. Even so, it's a good idea to unplug your computer during severe storms.
