File Name: ac and dc current .zip
DC is the kind of electricity made by a battery with definite positive and negative terminals , or the kind of charge generated by rubbing certain types of materials against each other. Certain sources of electricity most notably, rotary electromechanical generators naturally produce voltages alternating in polarity, reversing positive and negative over time. Whereas the familiar battery symbol is used as a generic symbol for any DC voltage source, the circle with the wavy line inside is the generic symbol for any AC voltage source.

- What's the difference between AC and DC power?
The AC current changes its polarity and magnitude periodically and continuously with respect to time. The Ac current can be produced with a device named alternator that produces the alternating current. Suppose a piston is inserted inside a pipe and connected with a rotating rod as in the pin pic below.
Difference Between AC & DC Voltage
Electricity flows in two ways: either in an alternating current AC or in a direct current DC. Electricity or "current" is nothing but the movement of electrons through a conductor, like a wire. The difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or "forward. A magnetic field near a wire causes electrons to flow in a single direction along the wire, because they are repelled by the negative side of a magnet and attracted toward the positive side. This is how DC power from a battery was born, primarily attributed to Thomas Edison's work.
Alternating Current (AC) vs. Direct Current (DC)
The major difference between the AC and DC voltage is that in AC voltage the polarity of the wave changes with the time whereas the polarity of the DC voltage always remains same. The other differences between the AC and DC voltage are shown below in the comparison chart. The voltage which causes the alternating current is known as the AC voltage. The alternating current induces in the coil when the current carrying conductor rotates in the magnetic field. The conductor when rotates cuts the magnetic flux and the variation of the flux induces the alternating voltage in the conductor. The dc voltages induce the direct current.
What's the difference between AC and DC power?
When the electricity was invented many changes have taken place over the years. The dark planet turned into a planet of lights. In fact, it made life so simple in all circumstances. All the devices, industries, offices, houses, technology, computers run on electricity.
However, the two appear to be more recently coming together to exist in harmony. Alternating and reversing direction 60 times per second 50 in Europe , AC current could be converted to different voltages more easily using a transformer. However, in recent years, DC has seen a bit of a renaissance. While both AC and DC current deliver electricity, the way in which that electricity arrives at its end destination differs. What are your appliances and electronics eating?
Direct current DC is the one directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors , insulators , or even through a vacuum as in electron or ion beams.

Теперь они выстроились в восемь рядов по восемь в каждом. Джабба посмотрел на экран и в отчаянии всплеснул руками. Новый порядок букв показался не более вразумительным, чем оригинал.

Стратмор бесшумно спускался по ступенькам. Незачем настораживать Хейла, давать ему знать, что они идут. Почти уже спустившись, Стратмор остановился, нащупывая последнюю ступеньку. Когда он ее нашел, каблук его ботинка громко ударился о кафельную плитку пола. Сьюзан почувствовала, как напряглось все его тело.
Это была предсмертная мольба. Энсей Танкадо незаметно кивнул, словно говоря:. И тут же весь обмяк. - Боже всемилостивый, - прошептал Джабба.
Читайте медленно и точно! - приказал Джабба.
