What the advantage of compensating winding for direct-current generators?
compensating winding is the one which is connected in series with armature winding & current flows in reverse direction to that of in armature .therefore the flux produced by this winding is such that to compensate armature reaction(effect of armature flux on main flux).hence voltage drop due to armature reaction reduces so terminal voltage of dc generator increases

They will first allow the banker to balance its books. The bank is said to be in "balance". It will also allow for proper reconcilliation of related, offsettng accounts. A hyp…otication is levveraged debt by pledging a note and bank asset as collateral for a loan. For example, a $1,000 CD can stand as the assurance for a $1,000 loan. Bank regulators are less concered with the credit of the borrower for an obligation secured by compensating balances which is a compensating collateral account or certificate of deposit.
compensating windings are used to overcome armature reaction
Winds generally come from different directions depending where you are on the planet. The equator to 30 o N the wind blows from the north east. The equator to 30 o S the wind …blows from the south east. 30 o N to 60 o N the wind blows from the west. 30 o S to 60 o S the wind blows from the west. if you are further than 60 o North or South, the wind blows from the pole. a diagram that illustrates why winds blow this way is linked here. http://en.wikipedia.org/wiki/File:Earth_Global_Circulation.jpg Ocean currents have no general flow, there are two different types, surface and deep ocean currents. Surface currents are linked here: http://en.wikipedia.org/wiki/File:Ocean_surface_currents.jpg The thermohaline current is a current that circulates warm water and cool water (thermo) as well as differently concentrated salt waters (haline) http://en.wikipedia.org/wiki/File:Thermohaline_Circulation_2.png
Winds tend to flow from west to east across the globe. However,other types of winds, such as trade winds over oceans, flowopposite to the main jet stream winds.
Tidal generators have the advantage over wind turbines in that the tides are regular and can thus be relied upon. For the tides to stop would mean the loss of Earth's moon - w…hich is a wee bit unlikely to happen any time soon.. Conversely, wind turbines rely upon the movement of air sufficient to turn the blades, and this cannot be relied upon.
Here are a few of the advantages: 1. We can generate cleaner energy to keep the earth clean. 2.We can generate energy more efficiently. 3.We can preserve our fossil fuels b…ecause they take millions of years for the Earth to make. Actually, none of those really occur and there is also millions of dead birds and bats. Wind systems are based on 28 mph average speed. If the wind goes over this, they shut down, under and power is cubically reduced. At 14 mph, wind gives us 10% and at 11 mph and it shuts down again. As a result fossil fuel plants run at 100% of rated to compensate for wind variables. The expected life of a wind system is shorter then the payback time. That means they actually are expected to cost us energy. They produce less energy then the energy it takes to build one! Hardly a good thing, but they feel so good.
Biggest advantage is that wind energy is free and renewable and does not release carbon dioxide into the atmosphere. Biggest disadvantage is that the wind does not always blow….
Under what conditions is it advantageous to generate alternating current in preference to direct current?
You can step up or step down an AC voltage -- power transmission without excessive energy loss. You can store AC energy in a passive element, requiring no batteries. AC signal… can propagate in air/space (wireless communication). You can moderate AC signals (FM, AM). You can store a lot of information in AC signals.

"In a compensation job, you would be responsible for making sure workers in a temporary position got their daily paychecks. This would be like working for Kelly Services, the …advantage would be that it is an easy job."
I have recorded that the wind usally blows west.
i want to know about the advantage and disadvantages
Tides happen with predictable regularity.
