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