A Diode is connected across a resistor and a voltage source in series, for biasing. The diode operating characteristics are like increasing exponential curve for current - vs voltage..
When a lot of current flows (higher power) through the diode, it gets heated up and its temperature increases, Then its resistance decreases. Then the operating point (Q point) of diode changes. Its operating characteristic curve also changes.
Answer: when the power dissipated by the diode increases or decreases....
