Extracted text: 37% 10:51 PM E EE_151_Presentat.. O GROUP ASSIGNMENT 5 Four circuit elements are connected in series across a sinusoidal alternating voltage given by10 sin (ut +30°) The instantaneous voltage across three of the elements are given by v, = 30 sin wt, v, = 60 sin (wt + 60') and v, = 30 sin (wt – 30°) (a)Determine the expression for the fourth voltage in the form A sin(Wt + B) (b)What is the r.m.s. value of v Use phasor diagrams. DO NOT use complex ni approach •..
