Yes, of course. The history is well known as to why 60 Hz was chosen. In the very early days there were many power systems and many voltages; even DC was used by some of the earliest power distribution
Your question is very broad. What do you mean when you say voltage "devices"? There are many. Are you just talking about voltmeters? or Ammeters? or both? I had a similar question a few years ago
I found some discussion about that in this paper: http://www.ti.uni-bielefeld.de/downloads/publications/diploma_theses/da03_mgrieg But, honestly I don't know the answer to it. I am
Oh, what a question. It is asked every day by someone. But, from a scientific point of view it is really a naive thought. What do you do when the sun does not shine? What do you do when the lights
To measure current with an ammeter the current must pass through the meter. So, the circuit must be interrupted whilst the ammeter terminals connected allowing the current to pass through the meter to
