Welcome back....

What happened at school.....No pictures ?

Here is a link that might be useful: Your previous post

i tried to get the pictures but i was told and i quote " if any pictures of this DANGEROUS electric problem get out of the school we can be fined and possibly closed down" therefore i dont have pictures. Yet...

and about the xbox cables. i tried to measure the voltage on the DC and AC settings on my meter and it was not registering any voltage but i touched the cable again and its a continual shock.

What kind of meter?

A digital meter will have an impedance high enough to measure from high impedance sources.

It is most likely capacitive leakage from 60 Hz and has a very high source impedance.
That limits the current and makes it more of an annoyance than a safety issue.

It shows up in switching power supplies if they are not well designed and grounded.

yes, it is a digital meter i tried to measure with. and i do know that the XBOX power supply is not grounded because it is provided with a two prong power cord.

If the digital meter cannot measure the voltage the source impedance is many hundreds of mega-ohms (higher then the meters input impedance on the voltage scale).

so does that mean it more of a nuisance than a safety hazard?

"so does that mean it more of a nuisance than a safety hazard?"

Yes.

The volt ticks operate the same way.

By having a very high impedance in series they limit the current to a level that is not a hazard.

Without the ability to deliver enough current even a very high voltage source is not a safety hazard.

ok thanks for all the help. have a nice day
