an emf , E=200 Sin 377 t volt is applied across an inductance L having a resistance of 1 ohm . the maximum current is found to be 10 A. find the value of L


Dear Student,
                       we know for L-R circuit  maximum current=E0R2+w2L2w is angular frequency=377so 10=2001+(377)2L2   ( square both side )we get 1+142129L2=400L=399142129=52mH
