The current in the circuit decrease slowly.

Explanation:

Given as:

For the electrical circuit

The voltage V in the circuit is slowly decreasing

The resistance R of the resistor slowly increasing after heating

Now, From Ohm's Law

Voltage is directly proportional to the flow of current through circuit

I. e V ∝ I

Or. V = R * I

where R is the proportionate constant and this is the resistance of the resistor

whose property is to opposes the flow of current in the circuit

So, If R value more then current I reduces in the circuit

∵ Here in the circuit, The resistance is slowly increasing, so, current I is slowly decreasing.

Hence The current in the circuit decrease slowly. answer
