An electric meter is a device that measures the amount of electricity consumed by a home or business. It records the energy usage in kilowatt-hours (kWh), which helps utility companies determine how much to charge customers for their electricity. Electric meters can be analog, with dials that spin, or digital, displaying usage on a screen. These meters are typically installed outside buildings and are connected to the electrical system. They play a crucial role in monitoring energy consumption and ensuring accurate billing. Many modern electric meters also have smart technology, allowing for real-time data transmission to utility companies, improving efficiency and service.
