Home electrical meters have been used for decades to measure electricity consumption, but the devices have never been reliable enough for everyday use.
That changed this year when the U.S. Environmental Protection Agency proposed requiring the use of ampere meters, or microamps, as a standard.
It’s a much more efficient measurement than a standard voltage, or watt-hour meter.
But there’s still plenty of room for improvement.
Here’s a rundown of how ampeers are measured.
Accelmeter: A common measurement for the home electrical system.
Acampers are commonly used for the measurement of current flow in the home.
They measure how much current passes through a resistor.
The higher the resistance, the higher the current, and vice versa.
The unit is usually called an ammeter.
Ampere: The unit of measurement for power consumption.
An amp is equal to the power consumed in a year by an average person, according to the U
