An elecric meter measured the amount of electricity consumed in units of ______
Answers
Answer:
The most common unit of measurement on the electricity meter is the kilowatt hour [kWh], which is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3,600,000 joules.
Answer:
Your electric meter records electricity usage in kilowatt-hours. In simple terms, 1 kilowatt hour = 1,000 watt-hours. For example, if you turn on a 100-watt light bulb for 10 hours, the energy usage is calculated as 100 watts x 10 = 1,000 watts (or 1 kilowatt hour).
How a Mechanical Analog Electric Meter Works
The traditional analog meter is a mechanical device found near the service entrance where the utility's service wires enter a building—either from overhead wires that enter the weatherhead and drop down through the conduit to the meter, or from underground service wires. The meter is usually encased in a glass housing and has a metal disc inside that rotates as the circuits inside the building draws current from the service wires. If you observe the disc, you can see that it moves slower at times of low electrical consumption, such as at night, and faster during peak usage times.
Mechanical meters use two conductor coils that create magnetic fields. One coil is affected by current going across the conductor; the other coil is affected by the voltage going across the conductor. Together, the magnetic fields created by the coils turn a thin aluminum disc at a controlled rate. (Aluminum is not magnetic but is moved in this case through a principle known as an eddy current). The disc turns a series of gears that move the five dials that record the electricity in kilowatt-hours.
This mechanism is called an indicator.
Your electrical consumption is read manually by a utility service person who visits the home to read the numbers on the dials. A mechanical electric meter cannot be read remotely. Your building's electrical consumption is calculated by subtracting last month's numbers from this month's reading.
A savvy consumer can learn to read these dials to gauge their own electric usage and verify that utility charges are accurate.
I hope this helps you.
