Do you mean definition? If so 110V = 110 volts-60hz = 60 hertz. Hertz is the cycles that the electricity runs at. 60hz. is the US standard. Europe is at 50hz.
Depending on the application and other factors, it will TYPICALLY be best to use a transformer. If it's a low current application, you can purchase a small 5V power supply transformer for under $20.00, US.
the voltage and frequency are 110v and 50(or)60hz because the devices which are invented in us are work at that voltage and it is efficient for that devices.
This is your lucky day. The standard mains supply everywhere in the US is 120 V AC 60 Hz.
A unit of electrical equipment is designed for operation at a certain voltage - or within a certain range of voltages - i.e for 5 volts, 12 volts, 120 volts. 220 to 240 volts. Originally the UK household alternating current supply voltage was specified at 240 volts or, more precisely, 240 volts RMS +/-6%, running at a frequency of 50Hz.Some time ago, to allow harmonisation across Europe, the specifications were changed to 230 volts RMS +10%/-6%, also running at a frequency of 50Hz.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. So, because 208 volts is lower than the minimum range of a standard 230 volt 50 Hz supply, it is not safe to assume that any equipment which has a rating plate saying that it should be powered from a 208 volts ac supply can be used on a 230V ac supply without causing any damage. Such damage might affect the equipment itself or its surroundings or its "human" users... If the Asker could use the discussion page - by clicking the Open Discussion button shown below this answer - to tell us exactly what the circuit is, which "demands 208VAC single phase", that information would be interesting to know. Then, maybe, a much more helpful answer could then be given here!
India's voltage is 230V so you need one that will convert from that to US standard.
A European hairdryer operates on 230V. US power is 110V. The hairdryer will need a high power converter that will be fairly expensive. (110V input to 240V output rated at about 800W) It will be less expensive to buy a new one at Walmart when you get to the US than it will be to buy a converter for the European one.
No India uses 240V at 50Hz the U.S. uses 110V at 60Hz.
If you are just buying speakers then they do not connect directly to a mains supply. Therefore, as long as they are connected to an amplifier with a suitable speaker output, they will work with no problem. On the other hand, if the speakers have an amplifier built in and are connected to the mains supply, they are unlikely to work on a 230V European supply if they are rated for a 110V supply. There are some exceptions to this such as multi voltage power supplies for example. If you are not 100% sure, assume that they will not work and avoid damage and personal injury.
Oh yes. They do provide 2-wire 220V and even 2-Wire 240V service in Europe. We went a different way in the States early on when we attached a center-tap wire in those same service transformers to provide 2 x 110V services, along with one 220V service. It is worthy to mention that 110V (220V) services in the US progressed to 115 (230V) and now stand at 120V (240V).
UK power supply is 230V at 50Hz. It is compatible with the rest of Europe but a continental to British connector adaptor will be required. For visitors from North America, note that the voltage is higher than US and Canadian standards. Some power supplies and equipment will operate on 90V to 260V so they will work with just a connector adaptor. That is the case for most laptop supplies. Other equipment may be fixed at 110V, in which case, they cannot be used safely in the UK without an additional power converter (a 230V to 110V transformer for example). Every power supply has the input voltage marked on it. Be sure to check each power supply before connecting it to a UK supply. Suitable connector adaptors are available in many hardware and electronics stores in England as well as in airport stores. Although the airports are the most expensive place to buy them, it saves a lot of time searching for stores that sell them. Note that the connector adaptors DO NOT change the voltage.
Yes it will work in India as most video games handle both 110v and 220v but cant be sure about games because India is PAL and US is NTSC.
No, different voltages, we have 230v supply, US 120v. There would be a big bang and lots of smoke, I did it at work once!
because India is far away from the u.s.
Answer for USA, Canada and countries running a 60 Hz power supply service. 220V in US, supplied as two separate 110V feeds. Your circuit breaker panel supplies both to large 220 V appliances (stove, A/C) and 1 leg=110V to regular circuits.
