The Electricity when generated is always in AC form. Some additional devices (like commutator, carbon brushes etc) to be used to conevrt the AC to DC form. It is very cumbersome, unviable. Concept of transformer is feasible only in AC form. Induction motor which a most common application is based on AC. Hence AC usage come into practice. Neverthless DC has certain advantages like less losses. Hence you find many high voltage transmission system is on DC voltage. Only direct source of DC is from Batteries.
What else can I help you with?
Do step up and down transformer only work with ac power or can you use them in dc only?
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
Who have sold more cds ac dc or metallica?
AC/DC, but only because there more widely known!
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
What are the benefits of using an inverter AC unit compared to a traditional AC unit?
Inverter AC units are more energy-efficient and quieter than traditional AC units. They can also provide more precise temperature control and have a longer lifespan.
Why is AC used?
The power source is AC. Hence AC is used. DC application is limited.
What are the advantages of DC to ac inverter?
Dc invereters are not well suited as compared to ac inverters.This is due to the reason because ac inverters are more efficient ,less dangerous and good for supply over distance.
Why ac motors are widely use than dc motors?
Because the power source available on a public power grid is AC. The reason AC is used is because there is less loss due to long distance wires in AC because high voltage lines can be used and easily reduced locally by transformers.
What are the differences between a window AC unit and a wall AC unit in terms of installation, efficiency, and cooling capacity?
A window AC unit is typically easier to install and more affordable, but may be less efficient and have lower cooling capacity compared to a wall AC unit. Wall AC units are usually more efficient and have higher cooling capacity, but they are more complex to install and generally more expensive.
What are the advantages of split AC systems compared to other types of air conditioning systems?
Split AC systems have several advantages over other types of air conditioning systems. They are typically more energy efficient, quieter, and provide better temperature control in individual rooms. Additionally, split AC systems are easier to install and maintain, and they offer a sleeker and more modern design compared to traditional window units.
How are ac schools in terms of education compared to other schools?
If you mean AC schools as Anderson County schools, there is nothing special or less of educations that you would receive, compared to another schools.
Why is AC widely used in transmition and DC is not?
AC is alternating current therefore for the same wire twice as much power is available also a transformer can be used to reduce the hi voltage to lower voltage easier. for interstate transmission DC would be prohibitive in size cost and power losses
What type of refrigerant is used in a ac?
R134A, R22A, R404A, R410A and many more
