The resistance of component $X$ decreases when the intensity of light incident on it increases. $X$ is connected in series with a cell of negligible internal resistance and a resistor of fixed resistance. The ammeter and voltmeter are ideal.

The resistance of component $X$ decreases when the intensity of light incident on it increases. $X$ is connected in series with a cell of negligible internal resistance and a resistor of fixed resistance. The ammeter and voltmeter are ideal.

What is the change in the reading on the ammeter and the change in the reading on the voltmeter when the light incident on X is increased?
