How to Figure out Watts, Power, Current, VoltageHansHermann Hoppe
In this figure, the blue lines represent lines that the electron beam is "painting" on the screen from left to right, while the red dashed lines represent the beam flying back to the left. When the beam reaches the right side of the bottom line, it has to move back to the upper left...
Born in Kansas City, Parker dropped out of school at 14 to start what would be one of the most important careers in the development of jazz. By his late teens, "Bird" the alto saxophonist was well on his way to becoming a seminal figure in jazz. A founder of bebop, he had a ...
Machino's Domain to rescue the world from an evil mega-polluter. Other games allow players to figure out the best alternative energy sources to build a green city, like in "SimCity Societies." NoteNiks has several games that teach kids how to recycle, compost and respect their environment....
In this figure, you can see that a relay consists of two separate and completely independent circuits. The first is at the bottom and drives the electromagnet. In this circuit, a switch is controlling power to the electromagnet. When the switch is on, the electromagnet is on, and it attrac...
Crunch the numbers and the final tally is another daunting figure. But then the total amount of electricity produced in the United States through all sources in 2007 was more than 4 trillion megawatt hours [source: U.S. Energy Information Administration]. And one megawatt hour is equal to 1...
Figure out how you are going to route the outlet pipe — usually 1.5 inch to 2 inch (3.8 to 5 centimeter) PVC. Running it up through a rim joist is usually the easiest way to get the pipe to the outside. Purchase your sump pump and liner together. The liner, essentially a heavy ...
For instance, if the base engine produces 200 horsepower, a turbocharger could potentially boost that figure to between 240 and 280 horsepower. One cause of the inefficiency comes from the fact that the power to spin the turbine is not free. Having a turbine in the exhaust flow increases ...
In order to figure out which areas need extra cleaning, Roomba Red has two dirt sensors located immediately above the agitator brush. These dirt sensors are acoustic impact sensors. When the agitator kicks up a large amount of dirt, the dirt causes more vibration when it hits the metal plates...
Let’s take a minute to explain how they function. To quote Harvard Extension School’sofficial YouTube channel, the “difference in total charge inside and outside of the cell is called themembrane potential.” (The term “resting membrane potential” derives from this concept. Go figure.) ...
