What is AC ( Alternating Current ) - Hindi / English

What is AC ( Alternating Current ) - Hindi / English 

Type of Current 
विद्युत धारा के टाइप

  • AC ( Alternating Current ) 
  • DC ( Direct Current ) 

AC ( Alternating Current ) 

एसी विद्युत् धारा जिसका मान एवं दिशा समय के साथ लगातार बदलता रहता है उसे AC करंट कहेते है यह करंट एक दिशा में 0 से अधितम तक तथा फिर उसी दिशा में 9 तक घट  जाता है और फिर दोबारा दूसरी दिशा में 0 से अधिकतम मान में बढता है और फिर उसी दिशा में 0 तक घट जाता है और यही क्रिया आगे चलती रहती है जिसके कारण इसकी अकर्ती तरंग के आकर्ती .जसी हो जाती है 

Alternating Current (AC)

Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.

Generating AC

AC can be produced using a device called an alternator. This device is a special type of electrical generator designed to produce alternating current.
A loop of wire is spun inside of a magnetic field, which induces a current along the wire. The rotation of the wire can come from any number of means: a wind turbine, a steam turbine, flowing water, and so on. Because the wire spins and enters a different magnetic polarity periodically, the voltage and current alternates on the wire

DC ( Direct Current )

एसी विद्युत् धारा जिसकी दिशा व मान समय के साथ नहीं बदलता जो हमेशा एक सामान रहता है DC करेंट कहेते है इसका एक सिरा पॉजिटिव तथा दूसरा सिरा नेगेटिव होता है इस तरह के करेंट का निर्माण सेल , बैटरी , DC जनरेटर के दुआरा किया जाता है  

Direct Current (DC)

Direct current is a bit easier to understand than alternating current. Rather than oscillating back and forth, DC provides a constant voltage or current.

Generating DC

DC can be generated in a number of ways:
  • An AC generator equipped with a device called a “commutator” can produce direct current
  • Use of a device called a “rectifier” that converts AC to DC
  • Batteries provide DC, which is generated from a chemical reaction inside of the battery
Using our water analogy again, DC is similar to a tank of water with a hose at the end.
