Because, I = V/R.

Here I is inversely proportional to R.

Therefore, if R increases (while V is constant) I decreases.

The above explanation is accepted if and only if in the date it is mentioned that external conditions like temperature, strain, etc remains constant.

Given that 'V' is constant,
V = IR.
I = V/R.

Here I is inversely proportional to R

So, if R increases I decreases.

Due to const volt it cause heating effect collision takes place hence resistance decreases and I decreases.

Ohms law state that current is directly proportional to the voltage and inversely proportional to the resistance at constant temperature.

But here constant voltage, then whats up.
