Alternating Current

A power transmission line feeds input power at \(2.3 \mathrm{~kV}\) to a step down transformer with its primary winding having 3000 turns. The output power is delivered at \(230 \mathrm{~V}\) by the transformer. The current in the primary of the transformer is \(5 \mathrm{~A}\) and its efficiency is \(90 \%\). The winding of transformer is made of copper. The output current of transformer is _________ \(A\).
