Re: Hair/blow dryer voltage question. 4 years ago. Save. Technically the mains in Switzerland is 220V, but varies between 210 and 230, and in the UK it is 240V, but can vary between 230V and 250V. In order to harmonise the EU created a new "standard" of 230V. Continental Europe would increase the mains voltage gradually to reach 230, and the UK

The adapter will take 100 - 240 V with a maximum of 1.6 A as input . This is the rating for which it will operate. You could give it 90 V but then it is not guaranteed to work. It needs at least 100 V but no more than 240 V. It will not take more than 1.6 A. So the plug is OK, since the plug can handle up to 10 A.
If you have a single lamp, you can use Ohm's law to calculate its resistance from the voltage and power rating; so a 120V, 240W lamp would have a resistance of 120^2 / 240 = 60 Ohms. If you take two of these lamps and put them in series and operate them at 120V, the series resistance will be _less_ than 120 Ohms.
Yes, you can connect your laptop charger to an electrical outlet in Singapore as long as the outlet is compatible with the charger's voltage and plug type. In Singapore, the standard voltage is 230V and the standard frequency is 50Hz. Most laptop chargers are designed to be compatible with a range of voltages (dual voltage), so they should work Original switch is AC 15A 125V / 10A 250V new one is AC 15A 250V / 30A 125V can i use it without damaging the appli Stack Exchange Network Stack Exchange network consists of 183 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Power (kW) = I (A) * V (V) You can use this kilowatt to amperes converter.
