What type of meter measures electricity consumption at a site?

• A. A watt-hour meter
• B. A voltage meter
• C. A flow meter
• D. A temperature meter

Answer: (A)

A watt-hour meter is the appropriate instrument for measuring electricity consumption at a site. This device records the amount of electrical energy consumed over time, typically expressed in kilowatt-hours (kWh). It is essential for utility companies to gauge how much electricity is used by consumers and to bill accordingly. A watt-hour meter tracks energy usage by taking into account both the voltage and the current flowing through the circuit, making it specifically designed for monitoring electricity consumption. In contrast, a voltage meter measures the potential difference in an electrical circuit but does not provide information about energy usage over time. A flow meter measures the movement of liquids or gases, which is unrelated to electricity consumption. Lastly, a temperature meter measures heat levels and also does not pertain to electrical monitoring. Thus, the watt-hour meter is the right choice for determining electricity consumption.
