A 240V to 24V step-down transformer takes a no-load primary current of 0.1A. The secondary current on no load will be
The answer is :- 4
No load means that no current flows in the secondary circuit. If nothing is connected to the secondary, there is no circuit so no current can flow. The current taken by the primary is due to the transformer behaving as a fixed inductor in this instance.
