Alternating current

Elemental particles consists of so -called electrons, electrically negatively charged. In the event of an alternating current, these electrons constantly change their direction, hence the name "change" current. From a socket in Germany, such an alternating current comes with one Tension of 230v. This is often abbreviated with AC, which comes from English and stands for "Alternating Current". The abbreviation DC then stands for the exact opposite, namely Direct current or "Direct Current".

The fact that one decided to change in the current networks instead of direct current was due to the simple conversion without major losses of interchangeable in direct current. In other words, this would not be so easy, which is why the high -voltage lines with three -phase alternating current or three -phase current are operated. The so -called single -phase change current is also common in the household area. However, if you have a lamp that does not need alternating current, but direct current, a simple one can transformer serve to convert.
