Alternating Current Diagram. Most commonly found in batteries direct current dc has a wide range of applications. Alternating current describes the flow of charge that changes direction periodically.
Alternating current can be defined as a current that changes its magnitude and polarity at regular interval of time. Alternating current ac is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current dc which flows only in one direction. Alternating current circuits 12 1 ac sources in chapter 10 we learned that changing magnetic flux can induce an emf according to faraday s law of induction.
Alternating current can be defined as a current that changes its magnitude and polarity at regular interval of time.
This is the 2nd topic of ac circuit series of chapter 07 alternating current chapter7. This device is a special type of electrical generator. One full cycle of alternating current is shown in the diagram below. Alternating current ac is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current dc which flows only in one direction.
