Some time ago, to allow harmonisation across Europe, the specifications were changed to 230 volts RMS +10%/-6%, also running at a frequency of 50 Hz.
Thus the mains supply voltage will remain within European Union norms (standards) even if it varies between an upper limit of 253 volts and a lower limit of 216.2 volts.
A 240 volt 50 Hz appliance can have up to 3 wires altogether:
but this is not required if the appliance is of the type known as "double insulated".
The hot wire feeds alternating voltage from the power station to the load and, because the voltage is alternating, the load draws an alternating current. Then the neutral wire returns the current to the power station to complete the circuit.
The United Kingdom and the Republic of Ireland (and some other countries elsewhere, most of which were formerly British colonies) use a power outlet plug and socket system which is totally different to the rest of Europe:
It is a very good plug and socket system but not many other countries have adopted it - probably because they didn't invent it!
Outside the UK and The Republic of Ireland (Eire), European countries use plugs where all the pins are round. Sometimes (but not always - it depends on the country) the plug's earth connection is not a pin but is a ground-socket within the plug which connects to a ground-pin which permanently protrudes from within the wall receptacle. That arrangement of pins and pin-sockets makes it impossible to insert a non-grounded plug into the receptacle! Another common European plug - the "Schuko" - does not use any earth pin but instead uses two clips which are positioned diametrically opposite one another on the outside edge of the plug.
230 for Europe
230 volts ac at 50 hertz.
230 volts ac at 50 hertz.
230 / 240 volts
The voltage is 230volts and this is the norm in Europe.
Sweden uses the standard European voltage of 230 volts (+10% -6%)
Your AC electrical service's voltage and frequency, and the types of plugs and sockets you can use, depend on the place where you live in the world.If you want more detailed information please see the Related Link and some Related Questions shown below.
An AC Adaptor is sometimes called a power supply or power adaptor; and is used for a variety of household products like, laptops, cell phones and cd players. It works by converting electric currents from the electrical outlet into a current that is compatible to the device.

There is no "positive" wire in an Alternating Current (AC) system, which is what a standard AC power cord or flex is used on. In a cord or flex for a small electrical appliance there is a always a "Hot" or "Live wire, a "Neutral" wire and maybe also a "Ground" or "Earth" wire. The "Hot" or "Live" wire is colored * Black in the US, Canada and other countries using a similar 60 Hz household AC power system.* Brown in Europe and other countries using a similar 50 Hz household AC power system. The "Neutral" wire is colored * White in the US, Canada and other countries using a similar 60 Hz household AC power system.* Blue in Europe and other countries using a similar 50 Hz household AC power system. The "Ground" or "Earth" wire is colored * Green in a cord or flex in the US, Canada and other countries using a similar 60 Hz household AC power system.* Green and Yellow in Europe and other countries using a similar 50 Hz household AC power system.

The main difference is that a simple AC generator is one meant for personal or household use that plugs into a wall's AC outlet. It is much less powerful than a power station generator, which usually must be wired into a main electrical supply. +++++ Errr, why would you plug a generator into a household mains socket? I'm glad I am not your home insurer!
