Colours: blue for NEUTRAL and black, brown or grey for PHASE.
A single electrical signal returns by the cable called NEUTRAL, that closes the circuit.
Produced in batteries and dynamos.
The distribution network is cheaper because the conductive cables are thinner.
Its transport via cable is subject to very high losses.
Abbreviated as DC in english and CC in spanish.
In Spain, uses a voltage of 230 V and a frequency of 50 Hz.
It is a system of three connected AC currents, produced simultaneously in the same generator.
It is the AC that arrives to our homes.
Circulates from positive to negative pole of generator.
Constant intensity and direction.
Periodically changes intensity and direction.
AC generators are easier to make, cheaper and need less maintenance.
230 V between PHASES and NEUTRAL and 380 V between two different PHASES.
Is abbreviated as AC in English and CA in Spanish.
PHASE conductor contains 3 cables differentiated by colours: black, brown and grey.
Has a single NEUTRAL returns cable wich colour is blue.
Can be easily turned into DC.
The frequency is also 50 Hz.
Can be stored in batteries to be used anywhere and anytime.
A single electrical signal is transmitted by the cable called PHASE.
The transport via cable has few losses thanks to the high voltage.
Is produced in electrical power stations.
