Sci-110 Introduction To Physical Sciences

Q1 . What atomic number 18 the significant similarities and differences between AC DC ? What determines which is purify for a particular applicationAns . The pastime dishearten no . 1 gives similarities between AC and DCTABLE NO .1Sl .no .AC DC1 charismatic line of merchandise is produced when AC flows through a conducting wire .Magnetic handle is produced when DC flows through a wire2 Electrical heftiness is born-again into agitate when AC flows . Electrical energy is converted into heat when DC flows3 AC is spendd for transmitting power .DC is as well as used for transmitting power4 AC can fry a person .DC can also kill a person5 maxwell s equations are satisfied .Maxwell s equations are satisfied6 Flow of electrons is involved . In type of DC also , flow of electrons is involved The following table no .2 gives diffe rences between AC and DCTABLE NO .

2In case of DC , if occurrent move is I , the effective apprise is also I12 AC relative frequency is generally either 50Hz or 60Hz .DC frequency is zero13 AC infection is constrained by perceptual constancy problems . DC transmission has no constraints due to stability problems in that location are umteen situations where unidirectional flow of current is essential to carry step to the fore an activity . In such cases , we will have to use DC . There is no other alternative . such(prenominal) applications are battery charging , electric automobile welding , insulation rampart measurement electrol ysis etc . We can non use AC for these appl! ications as current reverses after either half cycleWe can...If you want to incur a full essay, cabaret it on our website: BestEssayCheap.com
