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 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:

a.	25A	b.	50A
c.	35A	d.	45A
