What Does Electric Meter present in household measure? I've heard that it measures 'KWh'. But what exactly runs the Meter? Current/Voltage ??
The last DC power system in NYC was shut down recently. It was used to run the elevators in some buildings built there at the turn of the last century. In the rest of the world commercial power is AC. Neither the current, not the voltage is ever constant in an AC system. Wherever did you get such quaint notions?y voltage? voltage will be constant Right?
