Question

A power transmission line feeds input power at 2300 V to a step down transformer with its primary windings having 4000 turns. The output power is delivered at 230 V by the transformer. If the current in the primary of the transformer is 5A and its efficiency is 90%, the output current would be :
(A) 50 A (B) 45 A
(C) 35 A (D) 25 A

Answer 1

Answer:

B. will be correct answers

Explanation:

Mark the answer brainliests please

Answer 2

Explanation:

p = esis/ epip × 100

90/100 = 230×15 / 2300 × 5

45 a
