Since amps and volts are standard units, but HP is not, you need the power in watts to solve the equation. Since 1 HP = 746 W, the wattage in this example is: 746×30=22380W Step 2: Is the System a Three-Phase System? If yes, introduce a correction factor of 1.728, which is ...
This reaction in a single fuel cell produces only about 0.7 volts. To get this voltage up to a reasonable level, many separate fuel cells must be combined to form a fuel-cell stack. Bipolar plates are used to connect one fuel cell to another and are subjected to both oxidizing and reduci...
and it's measured inamps. The "pressure" pushing the electrons along is called thevoltageand is measured involts. For instance, a generator spinning at 1,000 rotations per minute might produce 1 amp at 6 volts. The 1 amp is the number of electrons moving (1 amp physically means that...
A silicon atom will always look for ways to fill up its last shell, and to do this, it will share electrons with four nearby atoms. It's like each atom holds hands with its neighbors, except that in this case, each atom has four hands joined to four neighbors. That's what forms th...

You may have already guessed a couple of problems that we'll have to solve. First, what do we do when the sun isn't shining? Solving Solar Energy Issues If you worry that your solar cells won't perform on a stormy day, you can always store the sun's energy in backup batteries. ...
This is characterized by recurrent tripping out of the main breaker when practically everything in the house is running but there are no electrical faults to be found. To solve this problem, you can either lessen the total electrical load or install a new larger main entrance panel with new ...
When tinypiezoelectriccomponents bend, they generate a detectable electrical charge. Imbed these components into clothing, run several dozen miles, and you could help solve the energy crisis, right? That idea isn't quite as far-fetched as it seems. Dance clubs have installed floors with piezoelect...
Actions like these can help determine malfunctions, solve a number of problems and be very important as safety precautions. Let's look a little closer at one popular brand of multimeter -- Fluke. Fluke makes several multimeters with a range of capabilities suitable for a variety of users. ...
Photo: The concept of voltage optimization: it converts power-line waves of different shapes and sizes into ones of just the right shape and size to run your equipment more efficiently.There are two main ways to solve the problem. The first is to have your own, simple step-down ...
