That's Correct!
It's Wrong!
In a step-down transformer, the voltage is decreased on the secondary side compared to the primary side. According to the principle of conservation of energy and the transformer equations, when the voltage decreases, the current increases, provided that power remains constant (neglecting losses). Therefore, the current in the secondary winding of a step-down transformer increases relative to the primary winding.
