Yes, in electrical items you can use anything in either 10%+-. Most anything has a 10% differential that will work just as well, even in mechanical items it may be more then +- 10%.
220-250 Volt, as is the main part of the Europan Community.
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.
No, the voltage difference is too high.
NO
Most US laptops can handle 220 Volts without any issues as long as you are using the appropriate plug adapter. However, it's always a good idea to double-check the voltage requirements on the power adapter label to ensure compatibility.
normally, appliance are built in 110v or 220v, applied in 100-140v and 200-240v. if your 250v appliance is common home appliance equipment, then 220volt is ok, i think. otherwise, you should ask the vendor for special power supply.
you get a transformer...
Yes. If the plug (cap) end of the 250 volt lamp is compatible to the receptacle the lamp would work. The light output of the lamp would not be very bright. Because the working voltage is halved so would the light output.
YES, Make sure to get adapter plug for India.
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
Yes you can - with a transformer. Maplin Electronics sell a converter that allows you to plug appliances that run on 110V into the normal UK mains. See the related.
No. You will need a transformer to step up the voltage and you will possibly need to convert the plug.
