an adapter is needed because the 50 or 60 refers to cycles or how many times elec. changes direction a second . an adapter is needed to change from 50 to 60 or vice versa 60 cycle is used in usa and 50 cycle is used in Europe
230V/50Hz
There should be no problem at all.
The voltage isn't a problem, you can run 220 from your house and use that to run a European appliance, the problem is whether the appliance is dependant on line HZ. European is 50HZ and US is 60HZ. If the appliance specifies 220/50HZ, it will probably give you trouble here. If it says 220V/50 or 60HZ
Actually, electrical current in Poland is 230V.
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
Yes, using a 220v-60hz microwave in Australia is fine. The voltage of alternating current supplied to homes in Australia is 220v. The frequency of the voltage is 50hz.
Swedish outlets have 230V, 50Hz like the rest of Europe.
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
Unless the computer has a switch on the back allowing you to use both dual voltages and frequencies, the computers internal clock will run faster.
yes, it can be used - single phase voltage of 230v. 50HZ is important
Yes, as long as the voltage is the same it will not cause any issues. The frequency, or Hertz, is only a problem for large electric motors and clocks.
A high voltage will certainly damage a low voltage appliance and perhaps set fire to other things nearby.
