\bold{ANSWER}

When a large current flows through a conductor for more time, then due to heat produced the conductor becomes hot, its length increases and area of cross section decreases so its resistance \bold{increases} .

Due to change in physical conditions, the conductor becomes non-ohmic and the graph between V and I may not be a straight line.
