Does transformer draw any current when secondary is open

Hello !
Since the secondary of the transformeris open, the primary draws only no-loadcurrent, which will have some copper loss. This no-load current is very small and because the copper loss in the primary is proportional to the square of this current, it is negligible.
Hope it helps
