120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
A high voltage will certainly damage a low voltage appliance and perhaps set fire to other things nearby.
No, 120 v is not enough.
UK is 220v
yes.
If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.
You don't, at least, not legally.
You will burn up your appliance!!!!!
Brazil has a nominal voltage of 220/380V.
No. Attempting to run an appliance on insufficient voltage can cause damage to the appliance and can be dangerous. Call an electrician and get him to install a 220v plug
Connecting a 220V appliance to a 110V power source can damage the appliance and potentially cause a fire. The appliance is designed to run on 220V input, so using a lower voltage can overload its components. It's important to use the correct voltage to ensure safe and proper operation.
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
This type of a transformer is known as a step up transformer.
