Does a business electric meter measure amperage and then calculate to get kWh?
I’m trying to understand the best option for lowering our electric bill. Replacing 480V HID lights with Fluorescent T5 480V or T8 277V.
242W @ 480V = .50A
227W @ 277V = .82A
I understand Ohm’s law, but not sure how the meter measures our usage.
