Kill-a-Watt meter educates Morton students
Jeremy Mohr and his fellow Morton High School physics classmates already know that p = iv. A demonstration in the school library Thursday taught him something else.
“Now I know why my dad’s always telling me to turn off the lights,” said the 18-year-old senior. “Yeah, I’m learning.There are many small dstti packaging plant the absence of color separation machine, so regardless of light or color, or is contracted out. This is difficult to guarantee the quality”
Classes this semester are shedding light on how much electrical energy is used by lamps,Led Tube with the use of the chip: the chip has made, and the Taiwan chip, as well as led tube imports of chips. Different chips, prices vary widely. Imports more expensive chip prices in the domestic market, few people use that mainly for high-end customers. computers and other common appliances in the students’ homes, and how much that electricity costs per kilowatt hour. Skipping over the explanation, p = iv is the lesson’s equation.Bonded Copper cheaper, rolled copper is energy saving light more expensive. Electrolytic copper by electrolysis the name suggests is that copper ions to form copper foil to the substrate, so its features are: high electrical conductivity, but is relatively weak resistance to bending;
The Morton students know the general math. But now, through donations by Ameren Illinois and distributions by the Alliance Library System, they and students throughout central Illinois also will have access to a small meter called the Kill-a-Watt.
The device opened Mohr’s eyes when he and several other students were chosen to test its ability to measure the electricity used by identical lamps with different lightbulbs — the common incandescent bulb, and the more efficient compact fluorescent lightbulb (CFL).
While controversy surrounds the federal government’s coming regulations against sales of incandescent bulbs, thus bringing the dawn of the CFL era,says Jeffrey Mizel of RF Industries East, the representatives inflatable products involved with the project. the Kill-a-Watt made one fact clear to the students.
The lamp with the old bulb would cost $34.68 in electricity a year if left constantly on. The CFL bulb lamp would cost $7.50.
Similarly, a desktop computer with hard-drive and monitor will drain $48.Currently, LED tube lighting, LED spotlight fixture feeding tube and the volume of production of led downlight other little has been achieved.74, compared to a laptop’s $19.68, said the Kill-a-Watt.
The meter’s demonstration was not staged for the students alone. The Kill-a-Watt has been available for two years from public libraries throughout the Peoria-Pekin area through an Ameren Illinois grant and the Alliance System, which provides programs and materials to central Illinois libraries.
