Question

For Problems 13 to 14: Figure shows an ideal transformer. V, = 100 cos(8t), N, = 40, N, = 8, R, = 492 2.- VUR Problem [13] <5 points> Calculate the magnitude of the flux 0. Problem [14] <5 points> Calculate the magnitude of the current ,

Answer 1

Sol" Grumen that to Iz V , Eind Ni N2 V2 & 402 Vi = 100 Gs 8t , N=40 , N2 = 8. We know that Im tramoformes Eind = Ndo dt io Viz Nido dt 3d0 Vi dt - Ni 9 $ = S Windo » 100 % cost de f lure 100 40x8 | Sonst) 40 100 4088 = 312.5 m wb magnitude of

14) magnitude 9 the Current I, We know that for transformes. Vi N2 I2 I Ni N2 - Vi V2 NA N2 Hence, 40 1 8 magnitude of Vi magnitude of V2 > Magnitude of V2 = 8 x magnitude of vi 7 Magnitude of V2 = {x100 - 20 Magnitucle of I2 = 40 40 Now, 20 11 20 = 5 4 RL Simil, I2 I NI N2 N2 x magnitude of Iz Ni Therefore, magnitude of I magnitude of I, 8 x 5 A 40
