The table shows the names and circuit symbols of some electrical components. Complete the table by giving the missing information.
A student wants to find the resistance of a light-dependent resistor (LDR) in a dark room. They measure a current of 0.16 A0.16\text{ A}0.16 A in the LDR when the potential difference across it is 12.0 V12.0\text{ V}12.0 V.
State the equation linking potential difference (voltage), current, and resistance.
Calculate the resistance of the LDR under these conditions.
The student shines light of different intensities on the LDR and measures its resistance. Sketch a graph of the expected results on a set of axes.
