We are tempted to say that the
electricity is something that was invented by the modern
people, but there are theories according to which the roots
of the electricity are dating from the ancient Egypt.
It is not just a theory without a
foundation. At few hundreds kilometers from the Egypt`s
East, where today is Iraq. There is the place where some
unusual pots were found.
In some of these pots were
watertight cylinders from copper; the asphalt glued the
cylinders into their openings.
The specialists who found the
pots in 1936 said that these were galvanic elements
that can be considered some primitive batteries. |

And when they were
remade it was proved that with those pots the electricity
could be obtained. But since in no one of the thousands of
pyramid and tomb shafts no traces of soot were found the key
question refers to the way in which the ancient Egyptians
got the light. The question is more acute if we think that
all the light sources of ancient Egypt, like oil lamps and
candles had to use oxygen to get the light and they also had
to leave soot. Some people may say that the Egyptians
obtained the light with mirrors but the ancient Egyptians
were using copper plates as mirrors whose quality was not
good enough to produce the light.
The light enigma was solved at hundreds of kilometers from
the Luxor`s North, at Dendera, in the Hathor`s temple.

The
pots found there were capable to function like lamps, as
some electrical engineers established.
The specialists reconstructed a model made from two arms
that reach into a bulb, close to a thick end; in the other
end they put a type of cable from where leaps out a snake
touching the arms of the model. The result looked very much
like a lamp.
As regarding the
electricity in Egypt today, it is of 220Volts that
alternates at 50 cycles on a second. If the device
can not accept 220 Volts at 50 Hertz, a voltage
converter is needed. |
The voltage converters are of three
principal types; if you want to buy a resistor-network
converter you will see that it is said to support between 50
and 1600 Watts. These types of converters can support
electrical appliance of high-wattage such as irons and hair
dryers, being light-weight. You have to know that these
converters are not the best option for the digital devices
and can not be used for long periods of time.
Because of their contain of cooper wire and big iron rods,
the transformers are pretty heavy but very good for
appliances that need low wattage such as radios, cameras,
camcorders, battery chargers, mp 3 players and note books.
The transformers offers better electricity, they can be used
continuously and they have a Watt rating of 50 or 100.
You can find a package that includes a transformer and a
resistor network, ideal for those needing two types of
converters.
