Question

Question 9 5 pts A transformer with a primary current I1 = 12236º A has a turns ratio of 3 : 4. What is the secondary current, 12? 0 16236° A 16248° A 0 9/27 A 9236° A

Answer 1

a) A transformer with a primary Current I = 12 L36° A has a turns ratio of 3:4 What is the secondary current Iz? Ange We know that a= ni = f _ Iz] 12 V, 1 l klhere a= turns ratio of transformer n = no. of turns on primary Dz z no. of turns on secondary Vi = Primary voltage V = secondary voltage I = Primary Current Iz = Secondary current know that from given data We I = 12 236° non2 = 384

From formula D = I 2 I I2 = I. ni 02 - 1x 130 x 3 I = 9 236 A Therefore, the secondary current Iz = 9 £360 A ie Option 'D'

This is the current I2 For the transformer....
