Electricity, electricity is something very required in daily life we pad modren century ini. Imagine something we do not know if the electrical current kit will probably have a lot of hassles and kesulitan.Listrik very useful in all things good for lighting home, turn on the water pump, run the washing machine, electric iron, blender, television, radio, DVD, refrigerator and others, that require the amount of energy listrik.Begitu well the benefits of electricity, even an electric-powered cars were already made, to reduce heating global pollution caused by vehicles, electric kaena sangatramah environment. Most people probably only know the word power, even though the electrical energy when examined more deeply, divided into two, namely electricity, AC electricity (alternating current), and electric DC (direct current). Mengapaliistrik divided into two blocks??. .. YAH is so, they also have important snagat position in our everyday lives.
* Electricity AC
AC power, it has an alternating current, when viewed in the oscilloscope this current has a waveform such as water waves. This current flow can be said to be rough because of the bumpy, AC currents are not able to run most electronic devices, the AC current is used for, running the AC motor, transmission and distribution of electricity from power generators to homes, industrial and other consumers.
* Electricity DC
Electrical DC, has a direct current, when viewed in the oscilloscope has the form of a straight flow, this flow include smooth flow because of its straight like a thread, and Kasra tiadak as the AC current power bergelombang.kebanyakan DC, as smooth can be used to start the elektronika.seperti instruments, television, radio, DVD, computers, mobile phones and aru DC motor DC source comes from a battery or power supply of the diode bridge.
