How does an electric meter function?

An electric meter functions primarily as a device that records the amount of electricity consumed over time. It works by measuring the flow of electrical energy that passes through it, typically in kilowatt-hours (kWh). This measurement reflects the total electrical usage of a household or business, enabling utility companies to determine billing amounts based on the energy consumed.

Electric meters achieve this by employing various technologies, including electromechanical components or digital electronics that count the number of kilowatt-hours used. Modern smart meters also provide real-time data and additional functionalities such as remote monitoring and time-of-use pricing.

Understanding the purpose and operation of the electric meter is essential for grasping how electric consumption is monitored and billed, making it a fundamental concept in electrical utility management. Other options do not encapsulate the primary function of the electric meter, as they either pertain to different electrical measurements or control mechanisms rather than the consumption aspect.
