Question:medium

A power transmission line feeds input power at \(2200\,V\) to a step-down transformer with its primary windings having \(2000\) turns. The output power is delivered at \(220\,V\) by the transformer. If the current in the primary of the transformer is \(2\,A\) and its efficiency is \(80\%\), the output current would be:

Show Hint

In transformers, power is conserved (approximately). For step-down transformers, voltage decreases while current increases.
