An Energy Meter is a device used to measure the amount of electrical energy consumed by a household or business. It tracks the flow of electricity in kilowatt-hours (kWh), allowing users to monitor their energy usage and costs. Energy meters can be analog or digital, with digital versions often providing more detailed information and features. These meters are essential for utility companies to bill customers accurately. They can also help users identify energy-saving opportunities by showing patterns in electricity consumption. Some modern energy meters are equipped with smart technology, enabling remote monitoring and management through smartphones or computers.
