Hydropower plants harness water's energy and use simple mechanics to convert that energy into electricity. Hydropower plants are actually based on a rather simple concept -- water flowing through a dam turns a turbine, which turns a generator. Here are the basic components of a conventional hydro...

A current is introduced, either from a battery or another source of electricity, and flows through the wire. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent magnet. Electromagnets are useful because you can turn the magnet on and off by...
The charts show the sources of the electricity produced in four countries between 2003 and 2008. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. Task 1 饼状图 - - 范文 答题 Some people believe that governme...
Many years ago I [DF] asked an electrical engineer/programmer Daniel Martin and a physicist friend Trudy Kappel how electricity really works - what's really going on. The ensuing argument ended finally with "well ultimately, we really can't say, completely." And even with the recent confirmat...
If mr. Thompson has a little understanding of the product and corporation that he is calling to sky, electricity will be more productive, hopeful, very important. It is effective center and was aware of loans to deal with mr. Davis calling this week. Forceful. Listen wrong. Purple and ...
The idea is to use electricity to coat a relatively mundane metal, such as copper, with a thin layer of another, more precious metal, such as gold or silver. Electroplating has lots of other uses, besides making cheap metals look expensive. We can use it to make things rust-resistant, ...
A player (such as a tape deck) re-interprets this pattern as an electrical signal and uses this electricity to move a speaker cone back and forth. This re-creates the air-pressure fluctuations originally recorded by the microphone. As you can see, all the major components in this system ...
