But,we know that in transformers,power is constant. A step-up transformer steps up the voltage and steps down the current to maintain a constant power. (also, step-down transformer steps down voltage and steps up the current). In this view,current is not directly proportional to the voltage right? how is it we can apply Ohm's law then?

i just wanted to know,if ohm's law is applicable to transformers. if yes,how?if no,how? its just my curiosity to know about it. please let me know.
