What does an electrical meter primarily measure?

An electrical meter primarily measures electrical consumption in kilowatt-hours (kWh). This is essential for utility companies to determine how much electricity a customer has used over a specific period. The meter cumulatively records the total energy consumed, which is then used for billing purposes.

While it is true that electrical meters can have features to indicate current, voltage, and resistance, their main purpose is to quantify the energy usage indicated in kilowatt-hours. This measurement provides a direct correlation to the cost of electricity consumed and reflects the overall energy expenditure of residential and commercial infrastructures.

Understanding this measurement is crucial for both consumers and electrical professionals, as it helps track energy usage, identify patterns, and facilitate energy management and efficiency efforts.
