The electricity works like this, one element is referred to as current (ampere), which requires a force (volt) that moves through an electrical conductor, commonly uses copper as opposed less resistance (ohm) so it is possible to transport electricity. Also you can use aluminum as an electrical conductor which opposes more resistance to the passage of the amps that copper, this type of driver is used in medium and high voltage for its low cost and being lightweight, gold and silver are the metals oppose each no resistance but the costs would be millionaires use.

In this time we are very independent of the electricity because since these phenomenon discover, we don´t know a life without this. We use for the school, work, in the house, for communication, personal things, to eat, etc, but we have to know some tips if the electricity failure, we can´t stop our life’s.
