What represents the number of watt-hours for each revolution of the disk in a kilowatt-hour meter?

The watt-hour constant is a specific measurement that indicates the number of watt-hours generated per one revolution of the disk in a kilowatt-hour meter. This constant is crucial because it allows technicians and electricians to calculate the energy consumption of electrical devices by correlating the number of revolutions to the amount of energy used over time. The watt-hour constant is essential for ensuring accurate metering and billing of electrical consumption, as it directly relates the mechanical movement of the meter to electrical energy usage.

The energy factor is a different concept that typically relates to the efficiency of devices or systems in converting energy from one form to another, rather than measuring the output of a meter. The power rating refers to the maximum amount of power a device can handle or produce but does not relate to the number of revolutions in a kilowatt-hour meter. The revolution index, while it may refer to the count of disk rotations, does not specifically address the energy measured per revolution as the watt-hour constant does.

Understanding the watt-hour constant is crucial for linemen in accurately interpreting readings from kilowatt-hour meters and ensuring that consumers are billed correctly based on their energy use.
