What was the name of the scientist who invented AC?
The name of the scientist who invented AC electricity is Nikola Tesla. Thomas Edison fiercely competed with Tesla over the type of current energy grids would use. Edison lost the 'war of currents' because his DC electricity was impractical for long range energy transmission.
Where are Minnesota power grids located?
in minneota
What is velocity modulation in klystron?
As we know in klystron tube drift space is assumed to be free of any electric field. Therefore, the high velocity electron emerging in the later period are able to overtake the low velocity electrons leaving the buncher grids. As a result of these actions, the electrons gradually bunch together as they travel down the drift space. This mechanism of variation in electron velocity in the drift space is known as velocity modulation.
How much electricity can a nuclear reactor produce?
Nuclear reactors vary in size the same way any engine does. On the small size, they could produce tens of kilowatts. On the large side they can produce gigawatts. Commercial nuclear reactors that provide power to electrical grids produce about half a gigawatt to about one and a half gigawatts. They do not produce power continuously, even if there are no problems. They have to be shut down periodically for refueling.
What does physical location mean?
Location is the position of people and landmarks and landforms on the earth. There is relative and absolute location. Relative location is describing the things around the place or thing you are looking for. Absolute location is the longitude and latitude.

Will all electric grids go down if magnetic bomb is dropped?
Many people believe that the electric grids will go down if a magnetic bomb is dropped. Some people think that this type of bomb does not actually exist at this time but is still important to prepare for in the future.
How do you measure dc currents in power grid by using current transformer?
You cannot measure DC current with a transformer. You can only measure AC current with a transformer.Another AnswerPower grids are generally a.c. systems, with d.c. being reserved for either very long-distance transmission lines, undersea cables, or as links between independent a.c. grids. to measure the currents in high-voltage a.c. lines, a current transformer's primary is inserted into the line, and its secondary reduces the value of that current to safe values for measurement and, very importantly, isolates the user from the h.v. system.

What is the conclusion in alternating current and measurement?
The only thing that can be concluded about alternating current is that it alternated at 50 or 60 Hz throughout the grids around the world.
What is DC power?
Direct current (DC or "continuous current") is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current. Direct current may be obtained from an alternating current supply by use of a current-switching arrangement called a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be made into alternating current with an inverter or a motor-generator set. The first commercial electric power transmission (developed by Thomas Edison in the late nineteenth century) used direct current. Because of the advantage of alternating current over direct current in transforming and transmission, electric power distribution today is nearly all alternating current. For applications requiring direct current, such as third rail power systems, alternating current is distributed to a substation, which utilizes a rectifier to convert the power to direct current. See War of Currents. Direct current is used to charge batteries, and in nearly all electronic systems as the power supply. Very large quantities of direct-current power are used in production of aluminum and other electrochemical processes. Direct current is used for some railway propulsion, especially in urban areas. High voltage direct current is used to transmit large amounts of power from remote generation sites or to interconnect alternating current power grids.
