Our high school physics professor had a strict rule, which was that no students were to even TOUCH any of the things on the prof's demo table at the front of the room. Sure enough, one of the things on that table was an oil-filled capacitor of about 10 microfarads, charged to six hundred volts. Every semester at least one student heard "I TOLD you never to touch anything up here on this table!"
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
