1. Rotating field is comparatively light and can run with high speed.
2. High voltage can be generate due to high speed and there is very little difficulty in providing high voltage on a stationary part than a moving part.
3. It is easier to insulate armature coils for high pressure usually generated (6.6 to 11 kV). Since the stator is outside the rotor, so more space is available for greater insulation required for armature winding.
4. Very little difficulty is experience in supplying the field magnet current as it is very low in comparison with the armature current

What is the difference between an ac generator and alternator?
When electrical current flows through a circuit it moves by electrons in one molecule in a conductor [wire] "bumped" against the next molecule causing one of that next molecule's electrons to bump into the next molecule of the wire. This is true of both Alernating and Direct current. The difference is that in Direct Current circuits, the flow is always from, and in ONE direction. With Alternating Current, the flow direction changes, first in one direction, then in the opposite. In other words, back and forth. One set [one forward and one back] is called a cycle. When one hears about cycles in AC, that indicates how many cycles occur in one second, thus US AC 60 cycle current means that the current changes flow direction 60 times per second. In most of Europe, I think, AC current is set at 50 cycles. The AC cyclic rate is determined arbitrarily by the windings in the alternator, AND the RPM at which the alternator operates.

law of comparative advantage(kaylop)
What are the examples of advantages?
I'm not sure how this is related to science and technology, so I'm gonna give a general answer. Being tall when you need to reach something that's out of reach of short people is an advantage. Having a torch or a lighter when you're in dark area is an advantage. Having a cellphone/compass/map with you when you're alone in a forest is an advantage. Hope that helps :P
What are four things Nikola Tesla Invented?
Here is one: In 1882, Serbian inventor Nikola Tesla identified the rotating magnetic induction field principle used in alternators and pioneered the use of this rotating and inducting electromagnetic field force to generate torque in rotating machines. An AC motor is an electric motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field.
What is the advantage of having soft iron core in the galvanometer?
The advantage of having a soft iron core in a galvanometer is that it enhances the magnetic field strength, allowing for more sensitive and accurate measurements of current. Soft iron can easily become magnetized and demagnetized, which improves the response time of the device. Additionally, the core helps to focus the magnetic field, resulting in a more concentrated and directed force on the galvanometer's coil, leading to better deflection and readability of the measurements.
How does Nikola Tesla's AC motor work?
Edison and Tesla came to technological blows in the late 1800s when Tesla's AC (alternating current) power systems that are used all over the world today came into competition with Edison's DC (direct current) power systems. As it turns out, Tesla's system was the better one. In 1882, Serbian inventor Nikola Tesla identified the rotating magnetic induction field principle used in alternators and pioneered the use of this rotating and inducting electromagnetic field force to generate torque in rotating machines. An AC motor is an electric motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field.

Your car dies when you disconnect your battery what charging could you be having?
This could also be alternator problems as in a bad diode in the alternator.
Why does the compass rose point north?
it doesn't, it points to Magnetic North which is somewhere in the north of Canada. A compass may point 20 degrees or more different from geographic north. The North pole of a magnet will point to magnetic north. The next question is why is the Earth magnetic, and why does it have a south pole magnetic near the North pole. I haven't seen a really good explanation. Something to do with the centre of the Earth having a layer of liquid iron that is rotating, and moving conductors generating a magnetic field. The Earth's magnetic pole has flipped over in the past and gone walkabout, as evidenced by magnetic records in rocks which solidified at different times.
Where is the 2000 Crown Victoria voltage regulator?
Inside the alternator. It's part of the alternator. If you are having problems with low or high voltage output, I'd recommend replacing the alternator as a unit.
