Ohm's law states that  electric current is directly proportional to voltage provided that physical conditions like temperature remain constant i.e.
V = IR

On the other hand ,

Power = Voltage * Current

So here it seems that higher the voltage lower is the current (i.e. current is inversely proportional to the voltage here which is against Ohm's Law.) .

Now my question is how do physicists explain this apparent contradiction ? Or maybe this not a contradiction because I am analysing things incorrectly?
