It depends on the conversion method but a high-power converter should work at at least 98% efficiency, in which case it would need probably 1.02 MW.

The amount of alternating current (AC) required to produce 1 MW of direct current (DC) depends on the efficiency of the conversion process. In an ideal scenario with 100% efficiency, the AC power would also be 1 MW. However, due to losses in the conversion process, the AC power input would typically be higher than 1 MW. The exact amount would depend on the efficiency of the conversion system being used.

What does current mean in current electricity?
Current, measured in Amps, is the movement of electrons within a conductor. In direct current (DC) circuits, the electrons are always moving in a single direction from the minus to the plus. In alternating current, or AC, the electron flow reverses 120 times each second (in the USA) or 100 times each second (Europe). This is the way electricity is delivered to homes in nearly all of the developed world. Without getting too much into technical details, alternating current allows the use of transformers which make generating, delivering, and using electric power more convenient, cost effective and safe. Current is the actual movement of electrons. Other important measures in electricity are voltage, which is potential force, or ability to cause electrons to move. Power, which is energy released and is measured by the current times the voltage. There are many other measures.
How much current is carried by lightning?
An average bolt may carry around 30kA of current.
How much current would a 15W light bulb draw if it had 120 volts applied to it?
Basically, Power = Current*Voltage Current = Power/Voltage Current = 15/120 Current = 0.125A or 125mA
How much more direct sunlight does the polar region receive than the equator?
The polar regions never receive any direct sunlight.
If no current flows through a load how much energy does it receive?
none. no current means no energy.
Why direct current cannot be used for domestic use?
Alternating current can be sent via cables much much farther than direct current.
Merits and demerits of direct current distribution?
In direct current the voltage and current remain the same at all times. Direct current is more efficient when traveling longer distances, but has a higher loss rate when distributing to many people and its much harder to change the voltage.
Is vac and watt the same?
No, VAC is in direct reference to Voltage Alternating Current. This is much different than VDC which is in direct reference to Voltage Direct Current. The term volts refers to all voltages and does not specify what type it is.
What form of electricity comes out of a Wave Generator?
It depends on how the generator is set up. Some will produce DC (Direct Current) and others will produce AC (Alternating Current). Where possible AC electricity will be produced as it runs through the grid without much loss of power.
What Type of current that almost all electronics devices use?
The question is much too vague. Electronic devices can be designed to allow for direct or alternating current. Examples are your home DVD player plugged into the receptacle which is 120 volt alternating current and your ipod which uses battery direct current power. Small portable devices are usually direct current (battery power ). The plug that comes with such devices is for charging the battery. Or the device may internally rectify the alternating current and turn it into dc power.
What is different between alternating current and direct current?
Direct current is constant - always in the same direction. Alternating current regularly changes direction; for example, in household current, 50 or 60 times (that is, full cycles) in every second.See the Related Link below for more information about the difference between alternating current and direct current.
What is difference between battery and mains electricity?
Mains supply provides alternative current while battery provides direct current.
How much is 12 pence in pounds?
The current rate of exchange gives about 1.53 USD for a British pound
Realation of current with power and time?
There is no direct relation of electric current and power. In order to knowhow much power (or energy) the current gives up, you must know what thecurrent is flowing through.The easiest way to describe anything through which the current is flowing isto measure and state its electrical resistance.Once you know the resistance through which the current is flowing . . .Power delivered by the current = (magnitude of the current, amperes)2 x (resistance of the path, ohms)The power is delivered continuously. Its unit is watts.Each watt of power means 1 joule of energy every second.
How much are direct tv rebates?
Direct tv rebate offers change throughout the year so there is not one set rebate price. Before you sign up with Direct tv, you should check their website to find out what the current deal is.
What is the full form of ac and dc voltage?
Full Form of A.C. and D.C. supply is : A.C.= Alternating Current D.C.= Direct Current Direct Current and Alternating Current are two methods for transmitting electricity. In Direct Current, the individual electrons start at the power source and travel all the way to and through the load (such as a light bulb) and all the way back to the opposite terminal of the power source. This technique works well for small applications where the electricity is not being transmitted over any great distance, and relatively small voltages are being used. When distance and high voltage are required, Alternating current is used. In Alternating Current, the direction in which the electrons travel is flipped, usually sixty times per second. This results in each of the electrons moving only a small distance before being pulled the opposite way. This technique of transferring electricity is much more efficient because each electron only moves across a small distance, making the maximum power that can be transmitted dependent upon how many ambient electrons are in a wire. While in Direct Current, the maximum power that can be transmitted is limited by how many electrons a wire can transport around the entire circuit.
