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 bill customers accurately. Electric meters can be analog, with dials, or digital, displaying usage on a screen. These meters are typically installed outside buildings and are connected to the electrical supply. They play a crucial role in monitoring energy consumption, promoting energy efficiency, and enabling smart grid technologies. Some modern electric meters can communicate data remotely, allowing for real-time monitoring and management of electricity usage.
