Like most other countries, you will find that in England we use voltages ranging from almost zero to a few tens of kV, depending on the application. ;)
However, assuming you mean the voltage supplied by 3-pin 13A mains sockets (type G) then from 1 January 2004 the mains supply should be 230V (-6%, +10%), 50 Hz (±1%). ie a range of 216.2 - 253V. This replaced the UK's former specification which was 240V ±6% (ie a range of 225.6 - 254.4V). Some "shaver sockets", similar to round 2-pin sockets (type C) found in mainland Europe, will supply 110 V, but be careful since they often have a dual mode 110V/240V.
Almost without exception, a.c. is used for the transmission and distribution of electricity in all countries. The exception are high-voltage d.c. links, which are used for extremely long distances, for international interconnection, or undersea links.
So, the UK (England is part of the UK) uses a.c. Its low-voltage nominal voltage is 400/230 V, three-phase, operating at 50 Hz.
No modern industrialised country uses d.c. power supplies.
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
For make a system balanced losses in power
We use the "MOTOR GENERATOR SET" to convert the DC power to AC power we use DC motor and ac generator in it. It is very efficient way to convert the DC power to AC power.
Direct current can be generated by a generator. Generators are not as efficient as alternators ( that generated AC power ). Vehicles use direct current but come equipped with alternators. The AC power is rectified ( changed to DC ) for use.
AC, alternating current is used to power electrical outlets in the U.S..
All alternators make AC power when they run. There are diodes in the alternator that convert it to DC. There is no practical way to alter this. There are some large alternators that have both types of outputs on them but they are for large trucks. With the advent of converters that you plug into aux power outlets in cars, there is no reason to use the alternator to generate AC unless you are looking at a very high current requirement.
the work is done in the power supply box (the metal box part in the computer, the one you plug the power cord into). It converts AC to DC via transformers, rectifiers, and voltage regulators and has extra circuitry in there to make sure that the voltage doesn't ripple (with the changes in the AC voltage) or spike (e.g., when you first turn it on)
Some SUVs may have electical outlets. Almost any vehicle can have a DC/AC power inverter installed to run AC powered devices. Make sure the output is enough for what you want to run, and follow the manufacturers instructions when installing.
Yes, they have electricity in Cuba. The Cuban power outlets are suited for use with the North American flat blade type electrical plugs (caps). In general the voltage in Havana is 110V AC 60Hz, but some of the newer hotels have 220 V AC 60 Hz as well.
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
Blenders plug into electrical outlets in your home so have AC current. That electricity may come from wind power, nuclear power plants, coal power plants, solar cells, hydroelectric plants or a combination of the above.
the car use dc current dear
You can't. You have to use the pedal's AC adapter or a Voodoo Lab Pedal Power AC. Pedal Power 2 is a DC unit; the Whammy is an AC unit.
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
THHN is used for AC power.
Some do, some don't. It depends mostly on the microcomputer's intended use and requirements for portability: desktop microcomputers require AC powerlaptop and handheld (e.g. cellphones, GPS navigators, PDAs) microcomputers use rechargeable battery DC power and only require AC power during rechargea few microcomputers use disposable battery DC power and never use any AC powerthe microcomputers in unmanned satellites usually use solar cell DC power, there is no AC power where they arethe microcomputers in manned spacecraft usually use fuel cell DC power, but depending on the computer this may be provided either directly as DC or through a power inverteras AC; these fuel cells also provide drinking water as a byproductetc.
