Concentrated Solar Power
Markets, Strategy, and Forecasts 2014 to 2020
The concentrated solar power market is set to explode despite environmental objections to the technology. The latest CSP launch, Ivanpah solar electric generating system is an engineering marvel that delivers on the full promise of solar energy.
Homemade Battery Using Seawater
There is no better way to learn about science that doing it right and you have to admit most of us love a good do-it-yourself project especially if it produces a cool and unexpected result.
Ohm's Law
The relationship between Voltage, Current and Resistance in any DC electrical circuit was firstly discovered by the German physicist Georg Ohm. Ohm found that, at a constant temperature, the electrical current flowing through a fixed linear resistance is directly proportional to the voltage applied across it, and also inversely proportional to the resistance. This relationship between the Voltage, Current and Resistance forms the bases of Ohms Law and is shown below.
Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.
