Do you open your CRT and adjust the focus??

oh, and i heard that if you touch both the neg and pos terminals of car battery with your hand, you will get a serious surprise

Not true, I've done that many times before. I'm by no means electricity savvy, so I can't remember the technical reason for this. Too much resistance in the human body to make a circuit? Cant remember... *shrug*

Only if you don't need the screwdriver, anymore. With 25,000 or more volts running around in there, you could zap off the tip of the screwdriver. If you're lucky you won't get a chunk of molton steel in the face.

I've been inside monitors and TV sets. It helps to know what you're doing.

okay, you have officially scared me. how can that energy instantly melt the metal in that screwdriver?

lol, it wouldn't.... he was being a bit dramatic. It may be 25,000 volts, but that doesen't mean sh!t if it's at 0.5 amps(which is a lot @ 25kV)

It *IS* possible to melt tools though, with enough amperage. Try dropping a wrench across a car battery sometime. :Q (If you want a darwin, that is).

the reason i believe him is because my father told me that his screwdriver slipped inside of the CRT monitor, and his screwdriver was all shot to hell.

LOL........

I dunno about #1. Whatever, I can't refute it, but it seems unlikely. Multi kV caps don't hold enough amperage to melt screwdrivers unless they are VERY large.

Definately negatory on #2. You can hold the terminals on a car battery all day long and the only thing that will happen is your fingers will get tired. Whoever told you that was an idiot. It's only 3V more than a standard 9V battery. Have you ever been "seriously surprised" by a 9v?

Didn't think so.

you need some serious resistance, and a jump, to get the voltage required do a shock.

that's how ignition coils turn 12 volts into 40,000. go ahead, put your hands on the terminals of a battery. i guarantee you wont feel anything. the electricity will be flowing through you, but you wont feel it. so dont worry about it.

How does an ignition coil turn 12v into 40kV again? Doesen't have anything to do with resistance. It does have something to do with collapsing magnetic fields, though.

Voltage is like pressure. 12v simply does not exert enough pressure on your skin to pierce its resistance.

Now if you were Gene Simmons and connected the terminals with your tongue...
