What is needed to generate AC electricity?
An AC generator (Alternator). A rotor is turned into a magnet by what is known as 'excitation' current. The rotor then induces AC current in the stator windings as it is rotated within it. This is AC, due to the fact that the rotor has a north and south pole, which alternately induces current in the stator windings. The exitation current is provided to the rotor via slip rings. Controlling this excitation current will also control the output power by suitable control circuitry. This is the same principle, whether it is a small domestic generator, a power station, a wind turbine, or a car alternator.
If 200V AC generator connected to 200V DC generator then what happens?
current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
What is the current called when electrons reverse regularly?
Alternating current aka AC.
What is the definition of ac electricity and dc electricity?
AC means alternating current and DC means direct current. The amplitude of AC voltage and current varies with time. Traditional AC electricity used in homes in the United States is a 60 Hertz sine wave. This means that 60 cycles of a sine wave occur every 1 second. Since AC voltage varies with time, the amplitude at each instant is different. The voltage changes from 0 to +Vpeak to 0 to -Vpeak and so on. Since the amplitude is always changing, the voltage quoted for AC such as 120 Vac for US homes is an average known as the Root Mean Square (RMS). The general formula for determining the amplitude of the voltage at any given time is: Vinst = Vpeak x sin(t) where Vinst is the instantaneous voltage at time t, Vpeak is the peak voltage, and t is the time. The relationship between Vrms and Vpeak for a sine wave is given by the formula Vrms = Vpeak / square root (2), so Vrms = Vpeak x 0.707 DC electricity does not vary with time. The voltage and current are constant at all times.
Generators can produce two types of electric current?
Absolutely! Generators can indeed produce two types of electric current: alternating current (AC) and direct current (DC). Let me break it down for you. First up, we've got Alternating Current (AC). This is the kind of electricity you'll find in most homes and businesses. AC changes direction periodically, meaning the flow of electrons alternates back and forth. It's like a little dance where the electrons keep switching partners, and it's super efficient for transmitting electricity over long distances. That's why the power from your local utility company is usually AC. On the flip side, we have Direct Current (DC). This type of current flows in a constant direction, like a straight line. You'll find DC in batteries – it's the juice that keeps your gadgets powered up. While it's not as great for long-distance transmission, DC has its perks, especially for certain electronic devices that prefer a steady and unchanging flow of electricity. So, in a nutshell, generators can play both sides of the current game, producing either AC or DC, depending on the application. It's like having a versatile musician who can rock out with different tunes depending on the audience. Cool, right?
What is frequency of Ac in EgyBt?
frequency of AC current in egyptis 50 c/s
How can you block ac current?
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
What is alternating current and give examples for this?
Alternating Current( AC ) constantly reverses itself as a result OS reversing electromotive force.One complete reversal is a cycle,and the number of cycles per second is the frequency of alternating current .The standard frequency of alternating current in the United States and the rest of North America is 60 Hz(1 Hz or hertz,equals 1 cycle per second )ex...Transformer,AC generator
Do strobe lights use ac or dc current to flash?
Strobe lights use ac or alternating current to flash. The frequency of 50 Hz is alternating current's frequency, coming in handy for its flashing.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
What is the purpose of a frequency converter?
A frequency converter converts "alternating current (AC) of one frequency to alternating current of another frequency." (Wikipedia) They are used to control the torque and speed of AC Motors. For more information go here: http://en.wikipedia.org/wiki/Frequency_changer.
What is frequency the current alternates in the US?
In the US AC current oscillates at 60 Hz.http://www.answers.com/alternating+current
How many directions does alternating current flow?
The frequency of direct current (DC) is 0 Hz. The current only flows in one direction, like the electrical system in your car. On the other hand alternating current (AC) as it suggests alternates back and forth from source to load and when graphed it looks like a sine wave. The frequency of this current can vary depending on the source and it's application. Take your house hold electrical system for example, it is AC current with a frequency of 60 Hz (in North America), which means that you will have 60 current cycles a second. There is a lot more to both AC and DC systems and their applications but that's the basic difference between the two.
What is the direction of the current?
Current flows from negative to positive for DC. AC the direction changes with the sinewave. eg. AC a frequency of 60Hz the direction changes 120 times.
How does a frequency inverter work?
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.
What kind of electricity used in train?
Ac current. Ac current is easily controlled for voltage and frequency. The diesel engine runs a generator that generates AC current for use in the electric drive motors on each drive wheel.
