Hi, Im a very noob... but interested in lot of things.. especially science things... Im from Italy so forgive my crappy english...
I decided to register to this forum cause I read some of the lessons about electic circuits here... and i liked them.
But there is a concept that I can't really understand... so I decided to ask for help...
I read about other few similar questions.. but I didn't "like" that much the answers I read...
Suppose I've one simple closed circuit, a battery connected to a bulb : if I measure the voltage before and after the bulb I'll get 9 volts right? But if I test with the two probes AFTER the bulb (or before) I'll get 0. Fine. I don't like this... I mean If I think only at tha part of the circuit I m testing (a piece of wire actually) I can see no voltage... BUT CURRENT! (the one comin out from the bulb).
Am I totally wrong in my reasoning? (maybe it is more like a philophical question...)
Thank you very much for your patience.
Have a nice day!
