Answer 1

Current current entering leaving The current in the windings are The current in the windings are out of phase hence the secondary voltage y phase opposition with the primary voltage V_1 = 120 v N_1 (N_2 = 1/100 V_Sec v_1 time v_2/N_1 = 120 time 100/1 v _s = 12000 v CRMS v_S v_sec (max) - s_2 time 1200 = 16970 . 56 v secondary voltage primary voltage current in the dots are same hence Relating: The secondary voltage is in phase with the primary voltage v_sec = v_1 time v_2/N_1 = 34500 time 1/14 .375 v_sec = 2400 v v_sec (max) s_2 time 2400 = 3394 . 11 v (therefore v_max =
