Here θ is the angle turned by the coil in time t so that θ = ωt where ω is the angular velocity of rotation of the coil. Therefore φ = NABcos ωt <br /> Since the induced emf is –dφ/dt, the instantaneous value of induced emf is NABω sin ωt <br />The maximum value of the induced emf is therefore NABω<br />MVhttps://www.blogger.com/profile/05910408858112321196noreply@blogger.comtag:blogger.com,1999:blog-32436271.post-37374563207659297482018-03-20T14:01:54.412+05:302018-03-20T14:01:54.412+05:30Question 4 under Kerala Engineering Entrance 2009 ...Question 4 under Kerala Engineering Entrance 2009 Questions (MCQ) on Alternating Current Circuits<br />Where can i find the derivation for induced emf=NABwKrishna Deshmukhhttps://www.blogger.com/profile/07097478831389474267noreply@blogger.comtag:blogger.com,1999:blog-32436271.post-27937114668237415782009-07-29T09:52:46.830+05:302009-07-29T09:52:46.830+05:30Heavy computation!Heavy computation!control valveshttp://www.meaincorporated.com/noreply@blogger.com
