What An Electric Meter Measures

A watt is the product of the voltage and amperage or current in an electrical circuit.

What an electric meter measures.

Current is measured in units called amperes it should come as no surprise then that a meter that measures amperage is called an ammeter. The standard units of electrical measurement used for the expression of voltage current and resistance are the volt v ampere a and ohm ω respectively. Like the mileage display in your car that shows you the total distance your car has traveled the electric meter displays the total. Typically it is installed at the point where the power lines enter your building.

The disk is turned by the electricity passing through the meter giving a readout of how much electricity you are using. Current is the flow of electric charge through a conductor. An electric meter is a device that measures the consumption of electricity used by your household as it passes into your home. In the past all electricity meters were mechanical devices that a utility employee had to read manually.

Electric utilities use electric meters installed at customers premises to measure electric energy delivered to their customers for billing purposes. An electricity meter shows how much energy you ve used and will dictate how much you are charged on a monthly quarterly or annual basis so it s vital to understand how to take accurate measurements. An electric meter or energy meter is a device that measures the amount of electric energy consumed by a building tenant space or electrically powered equipment. An electricity meter electric meter electrical meter or energy meter is a device that measures the amount of electric energy consumed by a residence a business or an electrically powered device.

Ammeters usually measure current in milliamperes also called a milliamp and abbreviated ma. They are typically calibrated in billing units the most common one being the kilowatt. Understand the parts of your analog meter also known as a dial meter and how it works. An ammeter which measures current.

One multimeter can take the place of a voltmeter which measures voltage. These electrical units of measurement are based on the international metric system also known as the si system with other commonly used electrical units being derived from si base units. Electric utilities measure the electricity consumption of their customers with meters that are usually located on the outside of the customer s property where the power line enters the property. Electric utilities use electric meters installed at customers premises for billing and monitoring purposes.

Your electric meter usually has between four and six dials that advance as a central disk turns. One ma is one thousandth of an ampere. 1 volt x 1 amp 1 watt. While there are several meter types a multimeter is the most economical as it performs several functions in one unit.

And an ohmmeter which measures resistance.
