You should revise your question as it is a very broad stroke of a question that is difficult to answer without being a little more specific. Are you asking why home outlets use AC while appliances use DC? Are you asking why Transformers step up AC voltage instead of DC voltage? Vaguely it's due to cost effectiveness, AC travels more readily across cables that have less copper wire and more insulation rather than the opposite for DC voltage/current. I need a more targeted question. Hope this helps.
Most of the motors are AC. Fans, Mixer, Industrial equipment, Aircon, vacuum cleaner, plenty of applications use AC motor
Volt meter; And 500kV AC voltages are not measured directly - potential transformers, or capacitors are used to step 500kV down to safe voltage levels for measurement purposes (usually 66-120 volts).
as diode allows current to flow only in one direction . it is highly used in the conversion ac to dc power supply as in chargers, voltage converters... also used in circuit isolation, as it does not work in reverse biased mode.
ac motor
The power source is AC. Hence AC is used. DC application is limited.
Domestic: 240 V AC, 50 Hz Industrial: 400 V AC, 50 Hz Plugs used for 240 V: BS-546 and BS-1363
Alternating current (AC) is easier to transmit over long distances than is direct current (DC).
Half- and full-wave rectifiers are used to convert AC into DC. That is the primary use of the rectifier in industrial applications. AC is used across the power grid, but to use electricity for welding, electroplating, electrorefining (of metal) and as a DC source for motors with special speed controls, the AC must be changed (rectified) to DC.
For big buildings like hospitals, hotels, airports, industrial buildings, and residential apartments the centralised air conditioning system is used.
because alternators which is used in generating station are desiged for 50 hz heigher or lower fequencies are not possible
Actinium (Ac) is a chemical element with the atomic number 89, located in the actinide series of the periodic table. It is a radioactive metal that is primarily used in research and some specialized industrial applications.

You can find parts for you industrial AC unit at the Home Depot or Lowe's. You can also find them on Amazon.com for a great price, probably even cheaper than one of these stores.
There are a number of places where you can purchase an industrial AC Unit. I would check out sites like Amazon, Home Depot, and Sears. Costco typically has some great selections as well too.
In short No,The UK and most of Europe uses 230V ac single phase for domestic and light commercial installations and 400V ac three phase for industrial and heavy commercial requirements.The confusion comes the fact that a lot of cables are rated for use up to 600 or 650V ac and have markings on the insulation showing this.The wiring regulations allow for systems up to 1000V ac but these are rare. Distribution circuits ie the underground or over head supply cables between power stations and substations use 11,000 33,000, 125,000 and even 400,000 Volts.The UK previously used 240 / 415V and a lot of Europe used 220 / 380V but this was harmonised in 1988 with effect from 1995 (these changes make no practical difference for the user) but a lot of equipment is still labeled 240V or 415V.
The two main types of generators used to produce electricity are AC (alternating current) generators and DC (direct current) generators. AC generators are commonly used in power plants and homes, while DC generators are typically used in portable devices and certain industrial applications.
