Sci-110 Introduction To Physical Sciences

Q1 . What are the significant similarities and differences mingled with AC DC ? What determines which is wagerer for a particular applicationAns . The quest table no . 1 gives similarities betwixt AC and DCTABLE NO .1Sl .no .AC DC1 Magnetic force theme is produced when AC flows by a wire .Magnetic field is produced when DC flows through a wire2 Electrical energy is born-again into hop up when AC flows . Electrical energy is converted into heat when DC flows3 AC is determinationd for transmitting power .DC is in like behavior 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 study of DC also , flow of electrons is involved The following table no .2 gives differences between AC and DCTABLE N O .

2In case of DC , if current period is I , the effective harbor is also I12 AC frequency is generally either 50Hz or 60Hz .DC frequency is zero13 AC transmission is constrained by perceptual constancy problems . DC transmission has no constraints due to stability problems there are galore(postnominal) situations where unidirectional flow of current is essential to conduct stunned an activity . In such cases , we will prolong to use DC . There is no other alternate . much(prenominal) applications are battery charging , electric welding , insulation impedance measurement electrolysis etc . We can not use AC for these applications as current reverses after every half cycleWe ca n...If you want to dawn a full essay, orde! r it on our website: OrderEssay.net
