Describe how you could carry out an experiment to show the relationship between potential difference and current for a light-dependent resistor when the intensity of the light incident on the LDR is varied. (6 marks so looking for 6 points thank youu)

connect ammeter in series to the LDR connect voltmeter in parallel to the LDR connect the LDR to the Battery use a table lamp with variable brightness in a dark room make a table with two columns of current and voltage turn off lights. turn on the lamp. vary the light intensity and take readings from the ammeter and voltmeter. draw a voltage vs current graph to see how the resistance changes.
