What does the register in a kilowatt-hour meter track?

The register in a kilowatt-hour meter specifically tracks energy consumption. It records the total amount of electrical energy that has been used over a specific period, typically measured in kilowatt-hours (kWh). This measurement is crucial for billing purposes and allows utility companies to determine how much electricity a customer has consumed.

While the meter may have components that monitor current flow and voltage levels, these are not what is being directly recorded by the register. Instead, the calculations from those measurements help determine the total energy consumed, which is ultimately reflected in the kWh reading. The power factor, which relates to the efficiency of electrical usage, can also play a role in energy calculations, but it is not directly tracked by the register in a standard kilowatt-hour meter. Therefore, the correct answer reflects the primary function of the meter, which is the tracking of energy consumption.
